Convection in cylindrical coordinates
WebAug 18, 2024 · Abstract This paper presents the results of fluid flow and convection heat transfer in concentric and eccentric annuli between two cylinders using a three-dimensional computational fluid dynamics model. Effects of rotational speed (n = 0, 150, 300, and 400 rpm) and eccentricity (ε = 0, 0.15, 0.3, 0.45, and 0.6) on axial and tangential velocity … WebJun 29, 2024 · Convection happens when there is a difference in temperature between two parts of a liquid or gas. Convection is where the hot, less dense part of a fluid rises, and the cooler, denser part sinks.
