I am simulating subcooled flow boiling and also CHF in rectangular microchannel using Fluent wall boiling model....my doubt is
1) can we use CHF model for simulating subcooled flow boiling
2) upto what heat flux we can use RPI wall boiling.....can we go upto critical heat flux and still use RPI model....??
3) while using CHF model I am experiencing convergence issues ......I have used Psuedotransient approach ....what should be the ideal time scale facator....
pls someone clarify
thanks i advance
