The problem of solving two‐dimensional, non‐isothermal, non‐Newtonian boundary layer flow is of great importance in treating ablation phenomena of glassy substances. Many organic or inorganic glassy materials are shear thinning especially when they contain gas bubbles. The liquid layer equations for viscous non‐Newtonian flow are integrated in the vicinity of the stagnation point, when non‐Newtonian flow deviations are caused by shear as well as by the pressure gradient. Numerical results for an ablating model substance with the physical properties of a silicaborate glass (Pyrex) but varying shear rate dependency are given at several altitudes.
