Diplomsko delo obravnava zasnovo in analizo posebnega usmernika pretoka, katerega zasnova omogoča kroženje delovne tekočine znotraj sistema magnetnega hladilnika ob čim manjših tlačnih izgubah skozi jedro hladilnika, ki ga predstavlja regenerator. Pomemben del naloge je bil zato posvečen raziskavam tlačnega padca toka tekočine skozi sestav usmernika in aktivnega magnetnega regeneratorja. V okviru dela so bile izvedene numerične analize, ter eksperimentalno preverjene s močjo meritev. Rezultati meritev so služili za karakterizacijo dinamike toke tekočine. Rezultati dela služijo za nadaljnji razvoj prototipa magnetnega hladilnika.

• Title: Development of flow rectifier for active magnetic regenerator

Abstract

The diploma thesis deals with design and analsys of special flow rectifier, design of which, allows circulation of working fluid within magnetic refigerator system at minimal pressure losses through the core of refrigerator represented by regenerator. An important part of the diploma thesis is dedicated to research of liquid pressure drop through the assembly of rectifier and active magnetic regenerator. In the course of work, numerical analyzes were made and verified with measurements. Result of the measurements were used to characterize dynamics of the fluid flow. Result of the work serve for further development on prototype of the magnetic refigerator.
