A numerical and an experimental study on transient mixed convection in a lid-driven enclosure have been investigateded (Ji et al. The temperature at the top lid is higher than that at the bottom wall, producing a stably stratified. The idea was to try both a grid-based and a particle-based method, and see which worked better for my situation. The dynamic mixer (Fig. The bottom of the cavity is free to move at a specified speed and the aspect ratio of the cavity is changed from 1. COMSOL Multiphysics Simulations of the Electric Field and Gas Flow in a Microwave Axial Injection Torch A. Furthermore, the effect of aspect ratio on the oscillatory instability is presented. viscous flow in a triangular cavity by efficient numerical techniques. mechanics problems. 1 Lid-driven cavity flow; 2. In this video, I will demonstrate the solution procedure for lid-driven cavity in ANSYS Fluent. This problem is modeled by the Navier-Stokes equations. Numerical simulations were carried based on finite difference method involving MacCormack relaxation scheme to validate the particular numerical scheme. The arrows in the velocity vector field are initially too small. For the implicit steps, preconditioned matrices are used using LU decomposition. The 2D regularized lid-driven cavity is a canonical internal fluid flow problem in which fluid convects in a sealed box as driven by a moving lid. Ghia and C. In this tutorial you will learn how to: • Read an existing mesh ﬁle in FLUENT. The left and right vertical walls are submitted to horizontal thermal and concentration gradients and they are moving in opposite directions. In the middle and lower parts of the cavity, ﬂuid tends to be stagnant, and heat transfer is mostly conductive. Alsabery, M. , - Numerical solution of variable speed lid-driven cavity is carried out with thermal radiation being considered using control volume approach and staggered grid and applying the SIMPLE algorithm. Moallemi and Jang [14] investigated mixed convective flow in a bottom heated square lid-driven cavity.
