Abstract

In the range of parameters Ro = 0 ... 0.0167 and Re = 118000 the numerical investigation of heat transfer and hydrodynamics was performed in rotating radial round tube with incline-tangential flow swirl at the inlet and flow 900 turn at the exit. It was found that the rotation of the channel reduces the overall flow resistance of the channel. Rotation of the channel towards the flow swirl has a slight advantage on heat transfer and flow resistance compared with the rotation of the channel against the flow swirl, that should be considered when designing a cooling system.
