MIXED CONVECTION IN A LID-DRIVEN SQUARE CAVITY FILLED WITH NANOFLUIDS
RESUMO
Mixed convection in a lid-driven square enclosure utilizing nanofluids is numerically investigated for various pertinent parameters. The governing equations are solved numerically with finite volume method using the SIMPLE algorithm. Comparisons with previously published work on the basis of special cases are performed and found to be in excellent agreement. The top moving wall and the left vertical wall are maintained at different constant temperatures while the right vertical and bottom walls are thermally insulated. Two cases were considered depending on the direction of the moving wall. Numerical solutions are obtained for a wide range of parameters. Copper−water nanofluid is used with Pr = 6.2 and solid volume fraction χ is varied as 0% to 20%. It is found that decreasing value of the Richardson number and increasing value of volume fraction of nanofluids causes an increase in the average heat transfer coefficient. The streamline and isotherm plots and the variation of the average Nusselt numbers at the hot wall are presented and discussed.
