Natural convection in tilted square cavities with triangular shaped top cold wall

Influence of presence of inclined centered baffle and corrugation frequency on natural convection heat transfer flow of air inside a square enclosure with corrugated side walls

“…The results show that the average Nusselt numbers for wavy wall channel are larger than those for a paralleleplate channel and the velocity of air for some locations inside the enclosure has influence on the thermal field. Saha et al [18], Sultana et al [19] and Adjlout [20] present a numerical study of natural convection in a square inclined enclosures whereas a constant heat flux was embedded either at the bottom walls or on a hot side wavy wall. The results of streamlines and isotherms show the variation in the average Nusselt number with different angles of inclination and either heat source sizes or hot wall undulation affects the flow and heat transfer rate in the enclosures.…”
