THE DESIGN AND ANALYSIS OF EXHAUST EJECTOR FOR TURBOSHAFT ENGINE
터보샤프트 엔진의 배기 이젝터 설계 및 유동해석
Abstract
An ejector is designed for the purpose of engine bay cooling and exhaust gas cooling. The primary flow of the ejector is the exhaust gas of the turboshaft engine. The mass flow of secondary flow is calculated by using the approximate analytic equation. For the purpose of verification of approximate method, comparison is made with the results of Navier-Stokes turbulent flow solution. According to the results of CFD, the mixing of two flows is incomplete due to the short length of mixing duct.
