Visualization Techniques of Differentially Heated Lid-Driven Square Cavity

Abstract

In the present study, an attempt is made to explore the flow field inside the differentially heated lid-driven square cavity. The governing equations along with boundary conditions are solved numerically. The simulated results (100 ≤ Re ≤ 1000 and 0.001 ≤ Ri ≤ 10) are validated with previous results in the literature. The convection differencing schemes, namely, UPWIND, QUICK, SUPERBEE, and SFCD, are discussed and are used to simulate the flow using the MPI code. It is observed that the computational cost for all the differencing schemes get reduced tremendously when the MPI code is implemented. Plots demonstrate the influences of Re and Ri in terms of the contours of the fluid streamlines, isotherms, energy streamlines, and field synergy principle.

MHD mixed convection and heatlines approach of nanofluids in rectangular wavy enclosures with multiple solid fins

“…For example, 43 , 44 applied this method for mixed convection by varying the direction of the lid-driven wall in basic square cavities and porous square cavities, respectively. Narayana 45 used heatline technique to investigate mixed convection in a half heated square cavity with the top surface being isothermal and moved to the right. Their study used normalised variable diagram (NVD) in getting better boundedness and accurate simulation.…”
