Numerical Analysis of the Effect of Fluid–Structure Interaction on Heat Transfer in the Square Cavity Using OpenFOAM

Abstract

The present study discusses the effect of fluid–structure interaction (FSI) in a square cavity with a top wall oscillating, i.e., sinusoidal variation of the velocity of the top wall. Due to this varying motion of the top plate, fin (flexible plate) starts oscillating in the transverse direction of the fin length. Due to flexible plate motion, fluid motion also gets disturbed, and because of this it can increase or decrease the heat transfer rate of the hot wall. For checking the effect of fin, flexible plate is set on the left, right and bottom wall. It is observed that incorporation of flexible flap on any wall decreases the heat transfer rate.
