Abstract

The paper presents methods developed for constructing equations for various finning surfaces. The methods are based on the theory of R-functions with their subsequent implementation on a 3D printer and the study of hydrodynamic and temperature fields in the poly-ionic finning of a TVEL shell. In the course of experiments with various methods of finning TVEL shells, more advantageous forms of finning, so-called polyzonal and chevron ones, were developed. Their implementation is proposed to be performed on a 3D printer. From the point of view of universality, one of the most promising is the functional representation with the constructive possibilities of the theory of R-functions. Results of the study of the velocity and temperature fields for different values of the twist finning parameters are given.

 

Keywords: R-functions theory; Ritz method; heat exchange; TVEL shell; polyzonal finning
