Fluctuating Free Convection Flow Along Heated Horizontal Circular Cylinders
ABSTRACT
Unsteady free convection flow of a viscous incompressible fluid along an infinite horizontal cylinder with a small-amplitude oscillation of the surface temperature about a mean temperature has been investigated. Using appropriate transformations, the governing equations reduced to local nonsimilarity equations for both the steady and unsteady parts of the solutions, which are obtained numerically employing the implicit finite difference method together with the Keller box elimination scheme. The effects of pertinent parameters, such as the Strouhal number, St, and the Prandtl number, Pr, on the local fluctuating skin-friction and heat transfer coefficients as well as on their amplitude and phase are shown graphically on the entire surface of the cylinder 0 ≤ x ≤ π.
