Numerical Solution of Natural Convection in a Vertical Channel.
Natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. The problem is a two dimensional developing buoyant flow. In this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. The results for the local Nusselt number at the du...

متن کاملConvection in a vertical channel
The flow generated by heat convection in a long, vertical channel is studied by means of particle imagery velocimetry techniques, with the help of the thermal measurements from a previous paper (Gibert et al 2009 Phys. Fluids 21 035109). We analyse the mean velocity profiles and the Reynolds stresses, and compare the present results with the previous ones obtained in a larger cell and at a larg...

متن کاملDirect numerical simulation of natural convection in a vertical channel
This study presents direct numerical simulations of natural convection for air (Pr = 0.709) in a vertical channel driven by differentially heated walls at Rayleigh numbers (Ra) up to 2.0 × 107. The present data is validated with that from Versteegh and Nieuwstadt [9] for Ra = 5.0 × 106. Using the present data for higher Ra, we appraise and compare the various proposed scaling laws for the mean ...
