WebAug 5, 2024 · example, the fin is again a cylinder, but there is convection from the tip. In the third example, the fin is conical in shape. In this case the mathematics of solving the differential equation is quite complicated, but the finite element approach is only slightly more complicated than the cylindrical fin case. WebIf your object is a cylinder in vertical orientation, the convective length scale is the height H of the cylinder. If your object is a cylinder placed horizontally the characteristic length is determined by the diameter D of the cylinder.
