  • Performance study on a hybrid solid desiccant-vapor compression air-conditioning system for hot-humid ambient conditions
    R. Venkatesh, Madhu Ganesh, R. Rudramoorthy
    Heat Transfer, 2025
    The paper focuses on the simulation and testing of a hybrid solid desiccant‐vapor compression air‐conditioning system under different hot‐humid climates. The simulation is carried out by a BLUEJ programming framework. Air at the lowest achievable temperatures from a solid desiccant cooling system is supplied to a standard vapor compression air‐conditioning system (VCAS). The cooling capacities of the hybrid system under three modes 1, 2, and 3, indicating different supply air conditions to the cabin, are reported in the paper. This paper expresses the trade‐off between having comfort conditions and reasonable comfort conditions inside the cooling space with energy efficiency as the inflection point. The more the study is moved towards the point of energy efficiency, the higher the reduction in the cooling capacities of the vapor compression air conditioner. This is demonstrated by the cooling capacity savings when the system is operated in three modes namely 1, 2, and 3. The substantial energy savings provided by Mode 1, Mode 2, and Mode 3 are 71%, 57%, and 37%, respectively. If the system is made to provide substantial cooling and focuses deeply on cooling capacity savings, then the system could save up to 77% in the cooling capacity of the vapor compression air‐conditioning system. If the system is made to operate solely with the milestone of comfort cooling for the occupants with any substantial savings in the cooling capacity of the vapor compression air‐conditioning system, then Mode 3 would deliver the milestone and give savings in the cooling capacities from 32% to 41% which is a significant savings. From the results of the performance study, it is inferred that the hybrid system provides significant energy savings compared to a standard air conditioner, especially in hot‐humid ambient conditions. The solid desiccant cooling system thus establishes itself as an effective pre‐cooler unit for a VCAS. The hybrid solid desiccant air‐conditioning in the paper is analyzed from the aspects of savings in cooling capacities of an existing vapor compression air‐conditioning system and comfort cooling. This is a newer operational approach, especially for using this hybrid solid desiccant cooling system for ambient humidity ratios greater than 15 kg−1 d.a.
  • Influence of anodization on the entropy generation in grooved heat pipes

    Heat Transfer, 2025
    The present research deliberates the influence of anodization on the entropy reduction in heat pipes that have grooved wicks and are charged with anhydrous ammonia fluid. Entropy generation analysis indicates how much energy is squandered because of the poor heat transfer surface, and the entropy must be minimized at any cost for a better environment. Anodization was performed to form a thin porous layer with micro/nanostructured pores in the grooved heat pipe's (GHP's) interior surface. The test findings demonstrate that the anodized thin porous layer enhances capillary rise and accelerates heat transmission. The entropy generation was computed by utilizing the heat transfer between the evaporator and condenser of a GHP and the drop in pressure across it. The second‐law efficiency and overall entropy generation are also examined in this study. The findings demonstrate that for a GHP with a groove size of 400 µm (0.4 mm) and a thin porous covering, the lowest entropy generation owing to heat transfer across a heat pipe is 0.015 W/K and the overall entropy generation is 0.02 W/K. Also, the same anodized GHP receives a maximum second‐law efficiency of 89.12%. This investigation revealed that the thin porous coating through anodization is the prime reason for the entropy reduction in the heat pipe.

    Proceedings of the Institution of Mechanical Engineers Part A Journal of Power and Energy, 2021
    The paper presents experimental data and results from a prediction tool for the performance of a desiccant loop cooling system. The experiments are performed under a variety of high humidity and hot ambient conditions and the system performance is described. One of the experimental conditions is typical of many Indian cities and the systems appropriate for those cities are established. A simulation program that can predict the performance of the desiccant loop is developed. The simulation results show that this system can work as effectively as vapor compression air-conditioning for certain ambient conditions whereas it can function as a pre-cooler to a vapor compression system under more severe conditions, resulting in a reduced power consumption. The results presented in the paper give a guideline to practicing engineers as to when a desiccant loop cooling system would be useful. A simple payback analysis and a lifecycle cost analysis shows that a desiccant cooling system with a waste heat recovery recuperator is an economically viable investment.

  • On Chaotic Behavior of Temperature Distribution in a Heat Exchanger
    Morachan Bagyalakshmi, SaiSundarakrishnan Gangadharan, Madhu Ganesh
    International Journal of Bifurcation and Chaos, 2017
    The objective of this paper is to introduce the notion of fractional derivatives in the energy equations and to study the chaotic nature of the temperature distribution in a heat exchanger with variation of temperature dependent transport properties. The governing fractional partial differential equations are transformed to a set of recurrence relations using fractional differential transform method and solved using inverse transform. The approximate analytical solution obtained by the proposed method has good agreement with the existing results.

    The effect of impingement cooling on the internal surface (cooling passage) of the leading edge region in a commercial turbine high pressure first stage rotor blade is investigated using Computational Fluid Dynamics (CFD) simulations. The flow domain is obtained by stretching the middle cross section (50% span) of the above mentioned blade. The simulations are performed for 3 different profiles in the cooling flow passage. In all the cases, the nozzle position and Mach number of cooling fluid is kept constant at E/D = 4.32 and 0.4 respectively. In the first case, the suction side profile is modified to facilitate shift in the vortex. This may reduce the crossflow effect, which will enhance the Nuavg. However, simulation results showed that Nuavg is reduced by 2% when compared to base case. In the second case, the coolant flow passage is smoothened at the apex to reduce dead zone and to enhance spreading of the jet. In this case, a 3% increase in Nuavg is obtained. Based on the analysis of velocity contours in the second case, the coolant flow passage in the third case is further modified to improve the spreading of flow. This resulted in 5% increase in the Nuavg when compared to base case.
