    Journal of Engineering Science and Technology, 2025
  • Enhancing Heat Transfer Performance in Heat Exchangers using Nanoparticle-Infused Fluids: A Computational Approach
    Wajeeh K. Hasan, Mohammed Ali Mahmood Hussein, Ali Najim Abdullah Saieed
    Cfd Letters, 2025
    The study examines the impact of hybrid nanoparticle-based materials on the flow performance in a tube with a consistent surface temperature of 373 K. The simulation of the flow was conducted using Ansys 2024 and two-dimensional governing equations for partial differentials. This simulation utilized three distinct concentrations of hybrid nanomaterials Al2O3–Cu to observe their effects. Al2O3–Cu nanoparticles are dispersed in water at volume ratios of 1%, 5%, and 100%. The fluid velocity varied between 0.1 and 1.5 m/s, while the input temperature was 25 °C (~298 K). The current study examines three cases of dimples: 15, 30, and 45 concave/convex dimples. Increasing the concentration of Al2O3-Cu nanoparticles in water is shown to improve certain physical properties while decreasing others. Moreover, when the concentration of nanoparticles grows, the Nusselt number (Nu) also rises. The thermal performance factor is enhanced with an increase in the number of dimples. The study shows that the heat transfer coefficient increases with hybrid nanoparticle concentration, achieving enhancements of 2.14%, 10.8%, and 21.82% for 1%, 5%, and 10% concentrations at 1 m/s. The highest increase of 22.22% compared to pure water occurs at 1.5 m/s with a 10% concentration. Compared to a smooth pipe, improvements are 15.67%, 30.01%, and 37.72% for three cases, with case 2 (30 concave/convex dimples) exhibiting the best thermal performance factor.

    Critical Reviews in Analytical Chemistry, 2024
    Veterinary pharmaceuticals have been recently recognized as newly emerging environmental contaminants. Indeed, because of their uncontrolled or overused disposal, we are now facing undesirable amounts of these constituents in foodstuff and its related human health concerns. In this context, developing a well-organized environmental and foodstuff screening toward antibiotic levels is of paramount importance to ensure the safety of food products as well as human health. In this case, with the development and progress of electric/photo detecting, nanomaterials, and nucleic acid aptamer technology, their incorporation-driven evolving electrochemiluminescence aptasensing strategy has presented the hopeful potentials in identifying the residual amounts of different antibiotics toward sensitivity, economy, and practicality. In this context, we reviewed the up-to-date development of ECL aptasensors with aptamers as recognition elements and nanomaterials as the active elements for quantitative sensing the residual antibiotics in foodstuff and agriculture-related matrices, dissected the unavoidable challenges, and debated the upcoming prospects.

    With the beginning of 2020, the Corona virus pandemic began, which negatively affected all of humanity, as medical and engineering research began to solve many problems faced by society during the era of the virus. Those who are exposed to this situation are among the medical staff responsible for treating and quarantining patients with the Corona virus. It has become the responsibility of engineers to develop solutions to the ventilation problem in order to limit the spread of this virus. Where the aim of this research paper was to study the effect of distance between patient and nurse and the effect of ventilation on the spread of the Corona virus. where a simulation model was created a room with real and 3D dimensions was studied with a patient lying down and the nurse treating him next to him. Where the room contains an air conditioner, two outlets for the airflow and an opening for the patient's mouth to simulate the exit of carbon dioxide gas from his mouth. Where the different and high speeds were studied to find out their effect on the spread of the virus abroad and its disposal. The result proves the best flow velocity of the ventilation system is 20 m/s, which led to a large limitation of the waiting for the Corona virus. The best place for the patient and the airway in the room should not be in the same airway, and the best place is between them. where these results serve as a reference for the engineering of medical rooms in terms of the effect of ventilation and distance of the pathogen on the spread of the Corona virus.
  • IDENTIFYING THE EFFECT OF CHANNEL WALL RIPPLE HEIGHT ON MULTIPHASE FLOW
    Mohammed Ali Mahmood Hussein, Wajeeh Kamal Hasan
    Eastern European Journal of Enterprise Technologies, 2022
    With the development of simulation technology and the ability to obtain accurate numerical results, as well as with the development of information technology, software that can solve numerical problems has become necessary to see physical changes that cannot be seen by the human eye. Multiphase stream field is settled utilizing the volume of fluid (VOF) method, and the flow equations are assessed and addressed mathematically by the notable limited volume approach. As a multiphase framework without mass exchange, air/water stream is considered. For practically all cases considered in this review, the heat transfer coefficient is higher. In any case, a critical punishment pressure drop was observed especially for high mass courses through undulating channels. A wavy channel with a variable wave height was simulated to see the variables of the flow process for multi-phase materials with a square cross-section, where different speeds were used for the inlet duct for air, water and steam. The results proved that the increase in the height of the channel wall wave works to obstruct the flow and thus increases the time required for the fluid to reach the exit area. The value of time required for steam and air to reach the exit area at the channel wall wave height of 25 mm and the flow velocity of 0.1 m/s was 6.01 s, which is the longest time it took for the fluid to reach the exit area compared to other cases. The pressure value reflects the amount of turbulence in the flow process, and it's crucial for thermal improvements based on flow turbulence. The entrance flow velocity is 0.1 m/s and the wall wave height is 25 mm at a time of 2 s, when the pressure reaches 873.7 Pa.
