Numerical investigation on heat transfer in an annulus between independently rotating cylinders with turbulent axial flow

  • Heat transfer in the air gap of two rotating cylinders was numerically studied, based on the mixing length turbulent model. Temperature field of annulus, temperature distributions and heat transfer coefficient distributions on inner cylinder surface were calculated and compared with experimental results. The results show that the mixing length turbulent model is applicable for the simulation of heat transfer in the annulus between independently rotating cylinders.
