Abstract

In this study, the numerical investigation of TRANSIENT NATURAL CONVECTION with respect to the effects of two-way fluid-structure interaction is presented in a square enclosure containing a FLEXIBLE BAFFLE. The enclosure is filled with air of Prandtl number 0.71. Temperature is constant in both hot and cold vertical walls, while baffle and horizontal walls are adiabatic. Arbitrary Lagrangian-Eulerian (ALE) formulation is used to describe the fluid motion in the given model. Non-Dimensional equations of the fluid domain with relevant boundary conditions are discretized by the finite volume method (FVM), and PISO algorithm is used to solve the pressure-velocity coupling. Non-Dimensional equations of the baffle motion are solved by the finite element method (FEM) and also the Newton-Raphson iteration technique. Rayleigh number changes over the range of 103 to 106. Among the assessed situations, 25 percent and 35 percent of them respectively, indicate increment and reduction in the rate of heat transfer compared with the enclosure containing a rigid baffle. Maximum and minimum values of Num,ss variation are 4.5 and -15.4 percent, respectively. Compared with the rigid baffle, about 90 percent of the assessed cases indicate an increase in the time to reach the steady state situations, which is not considered favorable.
