The paper presents a comprehensive investigation of mixed convection in a differentially heated grooved channel in the presence of an adiabatic baffle supported centrally from the top wall. Both assisting and opposing flow configurations are simulated using in-house CFD code for Richardson number 0.001–1000 and Reynolds number 10–200, considering a baffle height of up to 80% of enclosure height and air as working fluid. The flow and heat transfer characteristics have been analyzed using energy flux vectors, isotherms, averaged Nusselt number, and streamlines. The results show remarkable enhancement of heat transfer in the mixed convection regime in the presence of baffle.read more

Thermal management of heating element in a ventilated enclosure
TL;DR: In this article, the entire heating element was divided into multiple equal segments and positioned appropriately on vertical side walls, namely at bottom, middle or top location. And the performance analyses of segmental heating and whole heating were conducted for different Richardson number (0.01-100) and Reynolds number (50-200).

Magnetohydrodynamic mixed convection in a horizontal channel with an open cavity
TL;DR: In this article, the development of magnetic field effect on mixed convective flow in a horizontal channel with a bottom heated open enclosure has been numerically studied and the results indicate that the mentioned parameters strongly affect the flow phenomenon and temperature field inside the cavity whereas in the channel these effects are less significant.
