Abstract Theoretical -.Qioa’els are developed here to investigate effect of different operatin,,, parameters on the rewe¬ng process. The two-dimensio.nal conduction equation the claddin3 is solved for different geometries, to diet the rewet-Ging velocity and the temperature distrib¬on. The surface temperature at the wet front is tlken to b e the departure from nucleate boiling temperature.Two models are proposed. In the t-,-,,o regions model the face is divided into a wet reS,-ion with constant heat nsfer coefficient and dry region assmued to be adiabatic. the three regions model the cladding surface is divided o three different regions, a boilin. region immediately. |
