ABSTRACT
Flow boiling is an important component of convective heat transfer in nuclear power plants. In fact, it is the primary mode of boiling heat transfer in boiling water reactors, and it also occurs in the steam generators and other components of pressurized water reactors. The heat transfer coefficient when subcooled boiling occurs is a function of both the fluid velocity and the applied heat flux. The Klimenko correlation was developed in 1988, and it can be used to find the convective heat transfer coefficient until the liquid film disappears from the surface of the fuel rods. The Chen correlation was originally developed by J. C. Chen. It is a very popular correlation, and it has enjoyed considerable success since it was first introduced in the mid-1960s. The Kandlikar correlation is not as complicated as the Chen correlation, but it is very useful because it is applicable to fluids other than water.
