In the present paper, the heat conduction problem for the semi-infinite solid, with prescribed temperature and heat flux boundary conditions is solved. The Heat Balance Integral Method, based on an n exponent temperature profile is applied. One of the main concerns of this work is the determination of the parameter n, obtained using an energy balance in the solid. The literature classical solutions (Carslaw and Jaeger, 1959), were used in the comparison with temperature distributions obtained for several different values of n profiles, showing that the parameters selected in the present paper are the best ones. Different values were obtained for the prescribed heat flux and for the prescribed temperature boundary condition problems. The results obtained are useful for the design of the thermal protection systems in reentry space vehicles.
