Comparison of V-shaped rib and curve-angled ribs by computation heat transfer enhancement and pressure drop internally two-phase flow in two-pass channel

Abstract

In the present study two shapes of ribs are used to improve the heat transfer coefficient. Ribs are constructed in two types viz a V–shaped rib and curve rib. The ribs are used to improve the heat transfer. Heat transfer and space reduction while maintaining the durability of the design and thus better cooling and thus avoiding thermal stress. Simulation numerical solution by CFD with ANSYS WORKBENCH R1 2021 with in established turbulence model standard K-ε was conducted. The experiment performed for two-phase flow of water (8 L/min) and for air (16.67 L/min) at constant rib temperature about 60 °C. The study results show that the enhancement percentage in curve rib is about 90.3% while in V-shaped rib is 88.27%. The results showed that the curve ribs was the optimum design.
