An analysis of a steady laminar mixed convection boundary layer flow along a vertical cone of constant wall heat flux for any Prandtl number is presented. A mixed convection parameter [...], as proposed by Lin and Chen (1988), is used to serve as a controlling parameter that determines the relative importance of the forced and the free convection flows. New coordinates and dependent variabIes are then defined in terms of [...], so that the transformed non-similar boundary layer equations give computationally efficient numerical solutions which are valid over the entire range of the mixed convection flow from the forced convection limit [...] to the free convection limit [...] for fluids of any Prandtl number. The effect of the mixed convection parameter and the Prandtl number on the velocity and temperature profile s as well as on the skin friction and heat transfer coefficients are shown for both cases of buoyancy assisting and buoyancy opposing flow conditions, respectively.
