• Flow and temperature fields are studied of laminar boundary-layer flows past a flat plate of non-Newtonian fluid of the power law model taking account of the temperature dependency of its properties. Locally similar solutions of the fluid are investigated and calculated numerically to yield a general relationship of coefficients of friction and heat transfer. 1) Flow and temperature fields tend to have locally similar solutions at a greater distance from the leading edge, of which the Prandtl number P is larger for n<1 and smaller for n>1 (n : index of power law model). 2) Constants a and b which express the temperature dependency of viscosity and heat conductivity have influence upon velocity and temperature profiles through two ways of the variation of temperature itself and of its gradient, the former being distinguished far from the wall and the latter close to the wall. 3) Based on the numerical results, an approximate but accurate expression for coefficients of friction and heat transfer is given in terms of parameters n, a, b, and p.
