In this paper are analyzed, using high-order finite difference method, applications in which the viscous dissipation term can be neglected or not in the heat transfer equation. Some examples using various numerical values for the velocity field show that the viscous dissipation does not affect significantly the temperature field. Using the L2 norm, the numerical solution is compared with some examples that have an analytical solution
