WebHeat conduction from a sphere to a stagnant fluid. A heated sphere of radius R is suspended in a large, motionless body of fluid. It is desired to study the heat conduction in the fluid surrounding the sphere in the absence of convection. WebApr 11, 2024 · The previous studies on free convection from a cylinder, sphere and other axisymmetric shapes to power-law fluids found the following definition of the modified Rayleigh number Ω more useful than the usual definition of the Rayleigh number: (15) Ω C W T = G r P L 1 2 (n + 1) P r P L n (3 n + 1) o r Ω C H F = G r P L 1 (3 n + 2) P r P L n (3 ...
WebMay 1, 2011 · Initially, the sphere is at a uniform temperature Ts,0 and the fluid is in steady state motion due to natural convection. Close to the sphere there is a thin boundary … WebTools. In thermodynamics, the heat transfer coefficient or film coefficient, or film effectiveness, is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, ΔT ). It is used in calculating the heat transfer, typically by convection or phase transition ...
