摘要:
Extensive numerical study is considered and analyzed for investigating the effects of flow parameters on turbine disc cavity flow and heat transfer. Dimensionless mass flow and rotation Reynolds number are found to be dominant in disc cavity flow and heat transfer. Investigations show that the system total pressure loss increases with the increasing of dimensionless mass flow, and decreases with the increasing of rotation Reynolds number. Increasing of rotation Reynolds number strengthens the ef ...More
