Краткое описание

The free-convection boundary-layer flow at a three-dimensional stagnation point of attachment on a curved surface, due to an exothermic catalytic chemical reaction on that surface, is considered in this article. Using a suitable transformation of variables, the governing equations are reduced to a standard free-convection problem and then solved numerically for appropriate ranges of the Prandtl and Schmidt numbers and the local curvature parameter. Bifurcation diagrams of the surface temperature and concentration as a function of the ambient temperature are analyzed.
