... that travel upward to the cold cap and augment heat transfer from the glass to the cold cap. The CFD model employs the Navier–Stokes equations to solve for the fluctuating flowfield using a rigid body motion dynamic fluid body interaction module. This allows for movement of the floating body in response...
