Description:
Numerical simulation was performed to investigate convective heat transfer at the impinging zone of non-immersed pipe jet with Fluent in the ultra fast cooling process, and some influencing factors on heat transfer such as jet direction-to-plate angle, jet pressure (velocity), nozzle-to-impinging plate spacing (height), nozzle interval, nozzle diameter, and surface temperature of the plate were analyzed and designed. The results show that, in the ultra fast cooling process, the reasonable jet direction-to-plate angle is between 30 ° and 45 °; the economic water pressure is generally about 0.6MPa no more than 1.0MPa; since nozzle-to-impinging plate spacing (height) has little influence on the heat transfer coefficient due to the large water speed, nozzle-to-impinging plate spacing (height) is generally adjusted between 300 and 400mm; the nozzle interval should be set properly according to the dynamic relationship of the nozzle diameter and the jet acting zone, besides the maximum...
