Cylinder crossflow convection
WebHowever, there is a dearth of research on periodic MHD combined with convection [Citation 21–23]. Studying fluid flows around yawed cylinders [Citation 24–29] in the design of fluid equipment used in various industrial transport processes has increased interest in this area of study. Yawed-shaped bodies are used in a wide variety of ... WebAug 1, 2003 · The problem of cross-flow forced convection heat transfer from a horizontal cylinder with multiple equally spaced high conductivity radial fins on its outer surface was investigated numerically. The effect of several combinations of number of fins and fin height on the average Nusselt number was studied over the range of Reynolds number (1–200).

WebNusselt number. In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) is the ratio of convective to conductive heat transfer at a boundary in a fluid. … WebConvection Convection involves the transfer of heat by the motion and mixing of "macroscopic" portions of a fluid (that is, the flow of a fluid past a solid boundary). The term natural convection is used if this motion and mixing is caused by density variations resulting from temperature differences within the fluid.
