“…They noticed that at lower Richardson number, heat transfer rate is reduced for an oscillating wall than that for a constant velocity wall. Noor et al (2009) studied heat transfer in a square lid driven cavity with both top and bottom walls oscillating. The bottom wall was kept at higher temperature while the top lid was at cooler temperature and two vertical walls were adiabatic.…”

Laminar mixed convection in a lid driven square cavity with two isothermally heated square internal blockages is numerically investigated. The top lid of the cavity is moving rightwards with a constant speed. The two blockages are maintained at an isothermal hot temperature, while the walls of the cavity are maintained at a cold temperature. The flow and heat transfer behavior is studied for various placements of the blockages through analyzing the local Nusselt number distribution around the edges of the blockages and the average Nusselt number at the blockage surfaces at various Richardson and Reynolds numbers. Investigations are performed in a range of Reynolds number (100 -500), Richardson number (0.1 -10), and at a fixed Prandtl number (0.71). Computations are done using the ANSYS FLUENT commercial code based on a finite volume method. It is observed that, the average Nusselt number on the blockage surfaces increases with increasing Reynolds number at any Richardson number. The average Nusselt number changes significantly due to the change of blockage placement locations. The separation distance between the two blockages has large effect on the total average Nusselt number.

“…There is a distinct advantage in using a scheme that will allow equations (15) and (16) to be solved by means of tridiagonal forms only. Therefore, a fully implicit scheme, namely Alternating-Direction-Implicit (ADI) scheme is used for solving numerically these coupled partial differential equations (15) and (16).…”

“…Nouanegue et al [16] have investigated the conjugate heat transfer by natural convection, conduction and radiation in open cavities in which a uniform heat flux was applied to the inside surface of the solid wall facing the opening. Flow and heat transfer inside a square cavity with double-sided oscillating lids have been studied numerically by Noor et al [15]. Sivasankaran et al [25] have investigated a numerical study on mixed convection in a lid-driven cavity with non-uniform heating on the vertical side-walls of the cavity.…”

In this paper, we have used a streamfunction-vorticity (ψ-ξ) formulation to investigate the problem of 2-D unsteady viscous incompressible flow with heat transfer in a driven square cavity with moving top and bottom walls. We used this formulation to solve the governing equations along with no-slip and slip wall boundary conditions. A general algorithm was used for this formulation in order to compute the numerical solutions for the low Reynolds numbers Re ≤ 50. The numerical solutions of temperature are calculated for different Prandtl numbers 0.7 (for air) and 6.75 (for water). We have executed this with the aid of a computer programme developed and run in C++ compiler. We have proved the stability and convergence of the numerical scheme using matrix method. Heat transfer is studied by using the local Nusselt number. The uvelocity, v-velocity, pressure, temperature profiles along the horizontal and vertical line through geometric center of the square cavity, isotherms and isobars at different Reynolds numbers Re = 15 and 50 have been depicted.

An analysis has been carried out for the flow and heat transfer of an incompressible laminar and viscous fluid in a rectangular domain bounded by two moving porous walls which enable the fluid to enter or exit during successive expansions or contractions. The basic equations governing the flow are reduced to the ordinary differential equations using Lie-group analysis. Effects of the permeation Reynolds number , porosity , and the dimensionless wall dilation rate on the self-axial velocity are studied both analytically and numerically. The solutions are represented graphically. The analytical procedure is based on double perturbation in the permeation Reynolds number and the wall expansion ratio , whereas the numerical solution is obtained using Runge-Kutta method with shooting technique. Results are correlated and compared for some values of the physical parameters. Lastly, we look at the temperature distribution.
