Abstract

Analyzing the heat transfer coefficient at the liquid surface under forced airflow conditions is an important topic for improving thermal management in a variety of applications, including evaporative cooling devices, and electronic cooling systems. The aim of this research is to provide the theoretical relationships necessary to determine the value of the convective heat transfer coefficient at the evaporating liquid surface. Additionally, it uses both analytical and experimental methods to study forced convection heat transfer coefficients, emphasizing the increased accuracy of analytical results under turbulent conditions. The study also investigates heat fluxes from water evaporation, looks at the effect of forced convection, and simulates liquid pool evaporation by combining mass and heat transfer techniques. All things considered, the study highlights how crucial it is to precisely calculate heat transfer coefficients in order to improve the dependability and efficiency of thermal systems.
