A heater is placed in a pool of saturated water at one atmosphere pressure. The contact angle is 20◦. If at a wall superheat of 8K, the wall heat flux is 6W/cm2, calculate the size range of cavities that will nucleate and the corresponding waiting time. Choose two size cavities—one the smallest and one the largest. For the largest cavity, use the model developed in the chapter for a bubble growing in a non-uniform temperature field to calculate the bubble radius as a function of time. Plot your result.
