Natural and mixed convections in two parallel channels

Description
Reactor core reverse flow experiments were made to observe heat transfer and fluid characteristics of forced cooling failure accident of HTGR reactor core. Two channels (heated and cooled) were used in this experiment to simulate HTGR multi-channel core. Wall temperature, flow rate and temperature distribution in fluid were measured for natural and mixed convections. The results show that natural convection flow rate is proportional to Grashof number and that hysteresis between wall temperature and flow rate is observed for mixed convection. (author)
