Abstract
Abstract An analytical model for small-scale single drop fuel coolant interaction based on fragmentation caused by the Taylor instability and transient heat transfer during collapse and bounce period is developed. According to our previous analysis, pressure in the vapor film blanketing hot surface increases transiently more than 10 MPa, when thickness of the vapor film decreases less than 10 μm. The transient high pressure makes vapor-liquid interface bounce and causes the Taylor instabilities at both sides of the vapor-liquid interfaces by the large acceleration. As the growth time of the interface instability is enough short compared with the bouncing time, the instabilities result to fragmentation and mixing of both liquids. In the proposed model, the fragmentation time and fragmented particle size were estimated from the growth rate and the wave length of the instability. The analytical model composed of a set of time dependent differential equations was numerically calculated by the Runge-Kutta-Gill...
