Abstract : Using two parameter quadratic temperature profile in conjunction with the heat balance integral method, approximate solutions for the freezing of a semi infinite slab and inward freezing of a circular cylinder are investigated, with the assumption that the freezing takes place at the surface of the solidifying medium according to Newton's law of cooling. Comparison with the existing solutions on the former problem shows good agreement.
