CFD Analysis on Buble Growth and Bubble Departure in Pool Boiling

The process of bubble nucleation, growth and detachment are simulated using volume fraction method. As the bubble grows to a certain size, it will eventually detach from an active nucleation site, especially for the case of a pool boiling of a horizontal wall. Numerical results are compared with Distilled water and with Nano fluid of different concentrations. It is concluded that the departure diameter decreases as the wall superheat decreases, while the growing time increases.
