摘要: An experimental work is carried to study the characteristics of heat transfer and wetting front during quenching high temperature cylindrical block by water jet at atmospheric pressure. The surface flux are estimated applying a two-dimensional inverse solution. movements both transition boiling region over heated were observed using speed video camera. whole could be well. temperature, position time which maximum occurs obtained. It has been found that neither in front, nor but fully wetted region. also dose not start same when strikes block, it starts decreases value less than 170 °C.
