“…Kitamura and Kimura 13 studied the natural convection on upward‐facing plates and observed that the width of the plates significantly affects the heat transfer coefficients. Pattanayak et al 14 studied the natural convection heat transfer in water and observed that with an increase in heater width, heat transfer enhances. Sadafi et al 15 studied the evaporative cooling in saline water and stated that the usage of saline water enhances the performance of compact cooling towers by 8%.…”

Saltwater or brackish water is used as a coolant in most industries. Therefore, understanding the heat transfer processes and hydrodynamics during the natural convection in saline water is crucial for enhancing the efficiency of a heat exchanger. This study elaborates on the natural convection heat transfer in saline water under atmospheric conditions. A DC power supply is used to regulate the power given to the heater in a liquid pool for thermal analysis. The pool liquid comprises solutions with varying salinity from 0%, 0.2%, 0.5%, and 2%. The effect of varying salinity on the heat transfer coefficient and the thermal aspects encountered during the desalination process is analyzed. The temperature distribution across the surface
