RESUMO

The aim of the work is to analyse the behavior of the fluids water and air in laminar steady-state which natural convection flow around a vertical flat plate, considering both the uniform temperature and uniform heat flux cases and the variation of the properties with the temperature. The Finite Difference Method with the primitives variables is applied using a false transient approach in he energy and momentum equations. The algorithm was tested for following cases with similarity solutions: constant fluid properties with both isotherm and constant heat flux plate and variable properties with isotherm plate. The errors obtained were about of 2% ar less, in whole domain, except at the begining of the plate. The algorithm was used in the case of variable properties with uniform heat flux plate, which does not similarity solutions
