Effective thermal management remains essential for enhancing the performance and operational stability of modern electronic systems. In this study, a numerical investigation was conducted to examine the influence of mini-channel quantity on the thermo-hydraulic behavior of a modified heat sink configuration. Cylindrical mini-channels were integrated along the flow direction to enhance heat...

This study experimentally investigates the performance of a finned thermoelectric cooling structure designed to mitigate power losses in photovoltaic (PV) panels caused by temperature rise, as well as the effect of forced airflow applied to enhance heat dissipation from its hot side. Under standard test conditions, PV panels generate maximum power at a cell temperature of 25 °C, and any...

In this study, a vertical shell-type heat exchanger was used as the superheating-cooling unit in a vapor-compression heat pump. R417A gas was selected as the refrigerant, requiring no additional modifications to the system. The ambient temperatures of the condensers and evaporators used in the system were 22°C and 15°C, respectively, and the airflow velocities were 3.7 m/s and 4.6 m/s,...

Composite materials have become increasingly important in aerospace and automotive applications due to their high specific strength, corrosion resistance, superior fatigue properties, and inherent vibration damping capabilities. These advantages make them particularly suitable for lightweight structural components where performance, durability, and efficiency are critical design factors. In...

With the increasing importance of heat transfer applications, the development of new methods to increase energy efficiency and reduce energy consumption has become inevitable. In this context, the use of nanofluids as an alternative heat transfer medium offers higher heat transfer performance compared to conventional fluids, thereby reducing energy losses. Entropy analysis, a measure of energy...
