Abstract

V diplomskem delu je obravnavano hlajenje zavornega diska, s pomočjo metod računalniške dinamike tekočin. Tokovno polje je simulirano stacionarno pri konstantni hitrosti vožnje, prenos toplote pa je simuliran časovno odvisno. Zrak je modeliran kot idealen plin s konstantnimi lastnostmi, za material zavornega diska pa so izbrane lastnosti jekla. Po izvedeni analizi serijskega zavornega sistema vozila BMW serije 5, je v nadaljevanju obravnavana študija razmer pri vpihovanju hladilnega zraka in optimizacija takšnega sistema v smeri izboljšanja odvoda toplote. Rezultati opravljene analize prikazujejo pomembno povečanje hladilne moči pri implementaciji sistema za vpihovanje hladilnega zraka.

Secondary title: Optimization of disc brake cooling in a passenger car
Secondary abstract: In this diploma thesis the discussion is about optimisation of cooling of a brake disc, with methods of computational fluid dynamics. Fluid flow is simulated as stationary, at constant speed of driving, however heat transfer is simulated in a transient manner. Air is modelled with constant properties of an ideal gas and disc material as steel with constant properties. After the analysis of original braking system in BMW 5 series passenger car, work is continued with a study of the situation with use of external cooling air flow via cooling ducts. The system is optimised in aspect of maximising heat dissipation from the brake disc. Final results have shown, that cooling power is significantly increased with the implementation of external cooling air flow.
