### Laminar aiding and opposing mixed convection in a vertical channel with an asymmetric discrete heating at one wall

**ABSTRACT**

Detailed numerical simulations are carried out for aiding/opposing mixed convection in a rectangular channel with an asymmetric discrete heating. The governing equations are solved by the finite volume method using the OpenFoam® open source code. Based on streamline patterns, temperature maps, velocity and thermal profiles and Nusselt number evolution, an extensive analysis on the effects of Richardson number in the range -5 to +5 for both opposed and aided buoyancy on the fluid flow and heat transfer characteristics is presented and discussed.
