  • Multi-Objective Optimization of a Novel Supercritical CO2 Cycle for Waste Heat Recovery From a Gas Engine’s Flue Gas
    Md. Zahurul Haq
    Journal of Energy Resources Technology Part A Sustainable and Renewable Energy, 2026
    This article presents a novel optimal supercritical CO2 cycle for waste heat recovery (WHR) from a 1-MW gas engine’s flue gas. In this cycle, heat is absorbed from the hot flue gas in two stages. Following compression, the working fluid is split so that a portion can absorb heat from the hot CO2 leaving the turbine. Under optimal conditions, the low-temperature (LT) heater and recuperator efficiently preheat CO2, increasing the heat absorption from the engine’s flue gas and reducing heat rejection through the precooler, leading to increased output power and thermal efficiency. Hence, thermodynamic and economic models are developed, and two analyses and optimization cases using the differential evolution (DE) algorithm are performed. First, the cycle’s decision variables are optimized for maximum power output, yielding 181.67 kW of net power, and the levelized cost of energy (LCOE) is 0.1061 $/kWh. In comparison to recent studies using complex configurations under similar conditions, it produces more net power. The second case involves a 3E (energy, exergy, and economic) analysis and multiobjective optimization using the Pareto frontier, yielding a power output of 178.57 kW with an LCOE of 0.0922 $/kWh, achieving a 13.10% reduction in the LCOE with only a 1.71% loss in the power output. The present optimal cycle is a simple, compact, efficient, and economical WHR system for a gas engine’s flue gas.

  • Optimization of an organic rankine cycle-based waste heat recovery system using a novel target-temperature-line approach
    Md. Zahurul Haq
    Journal of Energy Resources Technology Transactions of the ASME, 2021
    Organic Rankine cycle (ORC)-based waste heat recovery (WHR) systems are simple, flexible, economical, and environment-friendly. Many working fluids and cycle configurations are available for WHR systems, and the diversity of working fluid properties complicates the synergistic integration of the efficient heat exchange in the evaporator and net output work. Unique guidelines to select a proper working fluid, cycle configuration and optimum operating parameters are not readily available. In the present study, a simple target-temperature-line approach is introduced to get the optimum operating parameters for the subcritical ORC system. The target-line is the locus of temperatures satisfying the pinch-point temperature difference along the length of the heat exchanger. Employing the approach, study is carried out with 38 pre-selected working fluids to get the optimum operating parameters and suitable fluid for heat source temperatures ranging from 100 °C to 300 °C. Results obtained are analyzed to get cross-correlations between key operating and performance parameters using a heat-map diagram. At the optimum condition, optimal working fluid’s critical temperature and pressure, evaporator saturation temperature, effectivenesses of the heat exchange in the evaporator, cycle, and overall WHR system exhibit strong linear correlations with the heat source temperature.
  • Development and Analysis of Adaptive Neural Network Control for a Cybernetic Intelligent 'iGDI' Engine
    M Abu Anas Shuvom, M Zahurul Haq
    SAE Technical Papers, 2015
    As combustion can widely vary between engine cycles if left uncontrolled, strict and robust control methodologies required to meet optimum performance at different operating conditions. Although the direct injection stratified charge engine development attempts started since 1920, lack of advanced instrumentation and robust real-time control techniques restricted its developments to common usages. In this research, novel intelligent control solutions developed and simulated on a Gasoline Direct Injection (GDI) engine. A research four cylinder 2.0 L GDI engine modeled with specific mechanical hardware along with adaptive control software that is frequently called as the conceptual Cybernetic intelligent GDI or ‘iGDI’ engine The engine modeled with Free Valve Actuation (FVA) hardware and precision fuel injectors connected directly to the engine cylinders that found assistive for control flexibility by technical assessments. Then a mechatronic neural network control approach proposed with adaptive control techniques. The engine and the controllers modeled and simulated with GT-SUITE and SIMULINK coupled simulation for control performance validation. Adaptive and predictive neural control architectures developed for multiple distinct GDI combustion modes. High volumetric efficiency (~99%) obtained overcoming pumping loss with throttle-less drive-by-wire operation. The neurocontrollers trained for time varying plant dynamics with Nonlinear Autoregressive with eXogenous Input (NARX) neural network. AFR set-point tracking achieved on ‘ECO’ mode with NARMA-L2 controller for minimum BSFC and NOx. On ‘POWER’ mode operation, maximum brake torque (MBT) obtained with NN predictive controller. Intake boosting provided by single stage turbocharging with intelligent controller methods developed and discussed. NN based controller algorithms developed, trained and simulated for dynamic control on cylinder firing events named as intelligent Dynamic Skip firing (iDSF) operation. Performance upgrades with the new hardware and software solutions discussed and shown graphically. It is clearly resulted that computational intelligence could effectively handle highly nonlinear dynamic real-time MIMO engine control problem with advantages of online optimization and adaptation feature.
  • Energy and exergy based analyses of a multi-fuelled SI engine
    M. Z. Haq, A. Morshed
    American Society of Mechanical Engineers Power Division Publication Power, 2013
    The paper presents energy and exergy based analyses of a single cylinder, four-stroke, spark ignition engine fuelled by six different fuels namely iso-octane, methane, hydrogen, methanol, ethanol and n-butanol. Wiebe function is used to predict realistic burn rates. Since the Wiebe function parameters are generally optimized for conventional fuels, the current study modifies them for different alternative fuels using available burning velocity data. Heat losses throughout the cycle have been predicted by empirical correlations. Analyses are carried out to quantify energy and exergy of the premixed fuel-air mixture inside the engine cylinder at various phases of the cycle and some results obtained from the study are validated against data available in literature. Both energy and exergy destructions are found to be dependent on the fuels and engine operating parameters. Results show that at 1000 rpm, about 34–39% of energy contained in the fuel is converted into useful work and this quantity is found to increase with engine speed. Exergies associated with exhaust are found significantly lower than the corresponding energy values for all fuels. The present study highlights the necessity of both energy and exergy analyses to probe and identify the sources of work potential losses in SI engines in various phases of the cycle.
  • Thermodynamic analysis of a multi - Fueled single cylinder SI engine
    M. Z. Haq, M. R. Mohiuddin
    ASME 2011 International Mechanical Engineering Congress and Exposition Imece 2011, 2011
    The paper presents a thermodynamic analysis of a single cylinder four-stroke spark-ignition (SI) engine fuelled by four fuels namely iso-octane, methane, methanol and hydrogen. In SI engines, due to phenomena like ignition delay and finite flame speed manifested by the fuels, the heat addition process is not instantaneous, and hence ‘Weibe function’ is used to address the realistic heat release scenario of the engine. Empirical correlations are used to predict the heat loss from the engine cylinder. Physical states and chemical properties of gaseous species present inside the cylinder are determined using first and second law of thermodynamics, chemical kinetics, JANAF thermodynamic data-base and NASA polynomials. The model is implemented in FORTRAN 95 using standard numerical routines and some simulation results are validated against data available in literature. The second law of thermodynamics is applied to estimate the change of exergy i.e. the work potential or quality of the in-cylinder mixture undergoing various phases to complete the cycle. Results indicate that, around 4 to 24% of exergy initially possessed by the in-cylinder mixture is reduced during combustion and about 26 to 42% is left unused and exhausted to the atmosphere.

  • Automated guided vehicles for industrial logistics - Development of intelligent prototypes using appropriate technology

    The industrial systems are recently leaning towards every possible means of automation for enhanced accuracy and better time management. But in case of developing countries like Bangladesh, the development of such sophisticated systems is not always cost effective for the manufacturers. Keeping this idea in mind, an initiative was taken to design and fabricate a low cost group of robotic guided vehicles to perform logistics in a quasi - industrial environment. The group consisted of two robotic vehicles those were capable of carrying certain loads and supply them to a predefined unloading location. An imaginary industrial environment was prepared in the laboratory and the robots went through several successful test runs which validated the efficiency and capability of the prototypes. The robots were prepared mostly with locally available materials and technology to reduce the expenditure. The manufacturing process also covered the use of appropriate technology. Both the robots were microcontroller operated and were re-programmable for introducing the possible changes those could happen in the industrial environment. The test runs were performed by programming them for maneuvering through both linear and curved trajectories. They consisted of tactile sensor feedback control to refine their positions in the destinations and deliver the load in an accurate orientation. The research proved the possibility of developing Automated Guided Vehicle Systems (AGVS) for the logistics purposes of local industries within a moderate cost limit.
