摘要: Abstract A numerical evaluation of the temperature field in an infinite solid medium that surrounds a cylindrical surface is presented. An unsteady and uniform heat flux density prescribed at surface, Cattaneo-Vernotte's constitutive equation for supposed to hold. The hyperbolic differential problem solved by MacCormack's predictor-corrector method assuming both thermal conductivity specific are temperature-dependent. Then, results compared with analytical solution available literature special case constant thermophysical properties.
