Effects of radiation on free convection from a heated horizontal circular cylinder in the presence of heat generation
Effects of radiation on free convection about a heated horizontal circular cylinder in the presence of heat generation are investigated numerically. The cylinder is fixed and immersed in a stationary fluid, in which the temperature is uniformly heated about the temperature of the surrounding fluid...

| description | Effects of radiation on free convection about a heated horizontal circular cylinder in the presence of heat generation are
investigated numerically. The cylinder is fixed and immersed in a stationary fluid, in which the temperature is uniformly
heated about the temperature of the surrounding fluid. The governing equations are transformed into dimensionless
non-linear partial differential equations and solved by employing a finite difference method. An implicit finite difference
scheme of Crank Nicolson method is used to analyze the results. This study determined the effects of radiation parameter,
Rd
heat generation parameter, γ and the Prandtl number, Pr on the temperature and velocity profiles. The results of the
local heat transfer and skin-friction coefficient in the presence of radiation for some selected values of Pr and γ are
shown graphically. |
