Abstract

Experimental results on convective and turbulence mass, momentum and energy exchange in pin bundle cooled by liquid metal obtained by electromagnetic and thermal track techniques are generalized. The basis for analytical models of convective, turbulence exchange by momentum and energy, as well as heat transport due to fuel pin beat conduction are presented. Correlations derived are analyzed in comparison with the other authors’ data. An influence of interchannel exchange on coolant and pin temperature distributions is illustrated by some examples.
