Paradox of the Darcy Free Convection over a Vertical Plate with Prescribed Inverse Linear Surface Heat Flux

ABSTRACT

It is generally accepted that the Darcy free convection problem for a vertical impermeable plate does not admit similarity solutions when the prescribed surface heat flux is an inverse linear function of the wall coordinate. The present paper explains why this is not unconditionally true, and gives the similarity solution of the problem in an exact analytical form.
