Bubble seed refers to nucleation phenomena at the origin of bubble formation. When the liquid is “seeded” homogeneously with a certain number of tiny vapour bubbles, theese will start to grow as soon as the liquid becomes “saturated” (P = Psat(T0 )) and correspondingly vapour volume fraction starts to increase as a result of phase change.

The bubble inception process is the dominating factor in nucleate boiling, which is why so much attention has been focused on this over the many years of study and experiment.

Dear Mr.Ramarajan J.

greeting

I'm absolutely agree with the definition of Dr. Ramarajan J. for nucleate boiling numerical simulation of bubble growth

where the nucleate bubble is creating when the liquid becomes saturation and the bubble size it is depending on many parameters like the heat source temperature, the surface finishing, propriety of the liquid ... etc

So I suggest to back to the reference

THERMO-FLUID DYNAMICS OF TWO-PHASE FLOW

by Mamoru Ishii

because you are not dealing with Tow Phase only but your case dealing with Tow Phase Change Phase and that mean there is heat transfer as a latent heat and the bubble meaning the amount of liquid that vaporized and make a bubbles of vapor.

with my respect

Dr. Ali Dawood Salman Thanks for your answer. It would be grateful if you can tell the procedure of introducing bubble.
