Study on enhancement of heat transfer and CHF in annular flow channel between rotating cylinders (2nd report)

摘要

Limited surfaces of diverter and target in fusion reactor and accelerator are exposured by high energy radiation beam from one side. A rotating annular flow with a rotor was applied to eraatnce heat transfer and critical heat flux, because Taylor vortexes and turbulence agitated by gear surface are formed in such flow. It is expected that a pulsating pressure by rotor with gear surface increases CHF. Heat transfer and CHF were investigated in various gear pitches, rotation velocities and subcooling.
