Laminarization of Low Reynolds Number Turbulent Flow in Heated Rotating Pipe
Biswadip Shome
Abstract:Numerical investigation of laminarization of low Reynolds number turbulent flow in a heated rotating vertical pipe is carried out using a rotation-sensitized [Formula: see text] Shear Stress Transport (SST) model with modifications to include low Reynolds number flow effects. The results show that rotation accelerates laminarization in heated pipes and leads to as much as 72% deterioration in heat transfer for a typical inlet Reynolds number of 5000 and at a rotation number of 2. Rotation causes a reduction of… Show more
