A phenomenological CHF model for mixing-vane spacers in a subchannel of a rod bundle
Abstract
A phenomenological model to account for the effect of a grid spacer with mixing vanes on CHF has been developed. It takes into the account of the mixing vane configuration (i.e., angle, number, position, etc.) on the flow field, the turbulent mixing between subchannels and heat transfer. Changes in flow field, turbulent mixing and heat transfer have led to CHF enhancement in subchannels and hence the bundle. The model has been implemented into …
