Short-Term High Temperature Failur

The balance between heat flow and fluid flow can be upset from either side; too much heat flow or too little fluid flow. In a waterwall tube, steam forms as discrete bubbles, nucleate boiling. When the bubble is large enough, the bubble is swept away by the moving fluid, and the cycle repeats.
