Abstract

The heat exchanger (HE) is a device that is used to complete the process of heat transfer between different matters without direct mixing. Therefore, it is of great importance in the transfer of energy and the completion of various energy transition processes. In the processes of HE between different energy systems, many factors influence and play a major and important role in the efficiency of transformation and exchange in forms of energy, such as the length, the material type, the exchange fluid, the surrounding environment, and many other factors. In this work, the effect of the HE length of the parallel and counter flow HEs was investigated based on the use of computer simulation programs. There was a significant impact of the exchange factors, especially the length of the HEs in both the parallel and counter-flow HEs, on the quality and efficiency of the HE and the temperature distribution. The overall evaluation shows that by increasing the length of the HE for both parallel and counter-flow HEs, the heat transfer is increased and the heat distribution becomes more homogeneous, which aids in enhancing the transfer of energy efficiency inside the HEs.

Highlights

Energy is one of the most important factors that affect the stability of any system, and dealing with different energy systems is very important to achieve the greatest possible benefit from energy sources [1,2,3]
We found many studies around the world concerned with traditional energy sources, determining their whereabouts and the best ways to benefit from them, as well as the matter of renewable energy sources, as many studies and evaluations of renewable energy sources have emerged as a solution and a basic alternative to traditional energy sources [7,8,9]
Where it is found inside the parallel heat exchanger (HE) with liquid water medium, the heat transfer was increased by increasing the length of the heat transfer as it was 42.9 kW for the length of 10 m, 47.6 kW for the length of 15 m, 49.5 kW for the length of 20 m, and 50.2 kW for the length of 25 m
