Mixed Convection Along Vertical Cylinders and Needles with Uniform Surface Heat Flux
Mixed convection along vertical cylinders and needles with uniform surface heat flux is investigated for the entire mixed convection regime. A single modified buoyancy parameter chi and a single curvature parameter lambda are employed in the analysis such that a smooth transition from pure forced convection ( chi equals 1) to pure free convection ( chi equals 0) can be accomplished. For large values of the curvature parameter and/or Prandtl number, the governing transformed equations become stiff. Thus, a numerically stable finite-difference method is employed in the numerical solution in conjunction with the cubic spline interpolation scheme to overcome the difficulties that arise from the stiffness of the equations.
