Abstract

Numerical simulations were performed to calculate the heat transfer coefficient of a perforated plate with cylindrical perforations arranged in a square pattern. The study varied three parameters: plate porosity (ranging from 0.1 to 0.3), Reynolds number (based on pitch) and the working fluid (air, carbon dioxide, or water). Perforation diameter and plate thickness were held constant. The Reynolds number was varied between 200 and 3000 for air and carbon dioxide, and between 500 and 7000 for water. The simulation results were presented in the form of Nu=f(Re·Pr) and compared with an empirical correlation for perforated plates with low porosity.
