Abstract:
Cooling water plays a crucial role in various industrial processes, particularly in petrochemical plants and power plants, where it serves to dissipate excess heat from machinery and heat exchangers. One common heat exchanger type is the double-pipe heat exchanger, where heat is transferred between hot and cold fluids through conduction and convection mechanisms. This study investigates the temperature profiles of cooling water in a double-pipe heat exchanger operating under high-temperature of hot fluid in order to avoid boiling in the pipe. Computational Fluid Dynamics (CFD) is employed to analyze the effect of cooling water Reynolds number on its temperature profiles inside the pipe. The research focuses on the relationship between the Reynolds number and the thermal boundary layer thickness on the inner surface of the pipe, as well as temperature variations. For the simulation scope, two pipe sizes: 30 mm and 25 mm, are used. The Re is set between 500 to 240000, and the hot fluid temperature ranges from 100°C to 250°C. From the simulation results, it can be observed that the larger tube (30 mm) exhibits a thicker thermal boundary layer and a significantly higher wall temperature (Twall) than the smaller tube (25 mm). As the Reynolds number increases, the Temperature wall/Temperature bulk Ratio increases while the thermal boundary layer thickness decreases, indicating enhanced convective heat transfer. Tube size affects flow dynamics, but both diameters in this study exhibit similar trends in improving heat transfer efficiency.
