Effect of cylinder proximity to the wall on channel flow heat transfer enhancement
We consider flow-through systems in which the characteristic length is limited such that turbulent flow is not reached even at high fluid velocities, i.e., the flow remains laminar. In these flow regimes, inducing circulation or vortices in the flow enhances mixing and heat transfer . These can be created by placing obstacles in the flow path, for example. Figure 1. Geometry of the simulation: Parameters D, are cylinder diameter, rotational oscillation amplitude and heat flux, respectively.
