hi all..
i am doing project of two phase flow(air and water)
superficial velocities of air and water are 1.5m/s and 0.45 m/s respectively...and the operating pressure is 1.4 bar
these are flowing thourgh a pipe of 26 mm dia . i am solving this in fluent.i need to find out volume fraction of secondary phase ..how can i find..plz help me .. please suggest me that ,which model is the best for my problem.
.....i have few days to submit.plz reply me as soon as possible
thanks for ur help......
