Natural convection over a vertical flat plate: A numerical and experimental investigation

Numerical analysis has been carried out for 2D steady state laminar boundary layer during natural convection over a vertical flat plate subjected to constant heat flux and verified with experimental results. The experimental test section consists of a vertical flat plate having dimensions of 355 mm...

description Numerical analysis has been carried out for 2D steady state laminar boundary layer during natural convection over a vertical flat plate subjected to constant heat flux and verified with experimental results. The experimental test section consists of a vertical flat plate having dimensions of 355 mm height and 177 mm width made from brass sheet. Temperatures of the heated plate wall and the adjacent heated air forming a boundary layer, is experimentally recorded at various locations under the heat flux of 250, 500, 750 and 1000 W/ m2 maintained on the plate surface. Numerical analysis for the constant wall temperature conditions have also been carried out for the purpose of validation.
