Określenie nieustalonego pola temperatury w ściance płaskiej przy zmiennym współczynniku przewodnictwa cieplnego
Applying successively the heat balance integral method and the optimal linearization method, the transient temperature distribution is determined in a plane wall with linear dependence of thermal conductivity on temperature, in two phases of heat penetration. The results obtained approximate fairly well the exact solutions.
