arunbaghel is on a distinguished road
hello friends,
I am doing a simulation of bubble growth in rectangular micro channel using ansys fluent (flow boiling), i have to simulate and analyse single bubble growth in fluent, i am facing problem of creating initial bubble (which is not stationary) which will grow in size, means water around bubble is super heated,basically growth of bubble in flow boiling
I will have to use volume of fluid and level set technique (coupled)
please help any hint, link any other form of help
or any other method of simulation without creating any initial bubble
