Abstract

Abstract:

The combustion chamber of the aeroengine is related to the degree and distribution of the oil spraying.Lots of tests for the spraying have been done.The clear and real flow area is very difficult to show through the window in the test.In this paper, the characteristics of the crack parallel spout flow were investigated experimentally and numerically.The results show that the flow film is possible to replace optic glasses for the tunnel window in a proper velocity ratio of the main fluid to the wind film.

Key words: parallel spout flow, w ind film, w indow s

V231.3
