Abstract
Thesis considers about flow simulation in nozzle to car conditioning unit. There is cavitation presumtion in the nozzle and objective is to complete mathematic model even with this effect. I engage the model for additional suction option of the third phase into the ejector. The third phase should be special polyalyglykol oil for compressor lubrication. There is also described function of whole conditioning system, function of De Laval nozzle for gasses and also cavitation theory in the liquid. Structured 2D mesh of ejector is created in Gambit and the whole model of nozzle is solved in ANSYS Fluent v6.3.26. There are also present proved parameters, which are needed for convergent result.
