Approximate analytical solutions of the local temperature variations, due to viscous heating, in channel flows of non‐Newtonian fluids with small Nahme‐Griffith numbers were obtained by the WKB‐J method. The results are general and easy to use so that extensive numerical computations are not required. Comparisons between the approximate analytical solution and complete numerical solution showed that the relative differences were very small.
