MIXED CONVECTION FROM AN ARBITRARILY INCLINED SEMI-INFINITE FLAT-PLATE .1. THE INFLUENCE OF THE INCLINATION ANGLE

The laminar boundary layer flow over an arbitrarily inclined semi-infinite flat plate, either heated or cooled, is studied to determine the influence of the buoyancy forces on the basic forced convection flow. The complete range of inclination angles including the special cases of the horizontal and the vertical plate is covered by taking into account both components of the gravity vector, normal and parallel to the surface. The systematical variation of free parameters is continued by studying different thermal boundary conditions and by variation of the Prandtl number (discussed in Part II). One remarkable result of this study is the finding, that for opposing buoyancy forces singular as well as regular behaviour can occur.
