Research Abstract |
A new model has been developed to analyze boiling explosion due to homogeneous nucleation. Boiling explosion caused by three different types of rapid heating such as(1) linearly temperature rise higher than 10^8 K/ s,(2) contact of liquid with high temperature surface(3) pulse heating of high heat flux of 100 MW/ m^2 level, can be explained and understood correctly by applying the new model. A temperature sensor with high response time of 10^<-6> second is newly developed. Its sensor makes it possible that a cooling curve obtained by quenching high temperature surface with liquid is much improved together with inverse solution developed by us.
