Abstract
A new method is proposed for performing thermophysical calculations of a core with fuel elements whose cross sections are cross-shaped. The method is based on the concept of equivalent roughness. The equivalent roughness parameters are chosen in accordance with the experimental values of the coefficient of friction of the assemblies consisting of these fuel elements and then the coefficient of heat emission and the critical heat flux are taken into account. The computational formulas used in this method are different from the conventional set and are physically better grounded.
