AERODYNAMIC DESIGN AND NUMERICAL ANALYSIS OF AN SMALL SIZE AXIAL AIR TURBINE
소형 축류 공압 터빈 공력 설계 및 수치 해석
Abstract
Air Starter motors are used for the start of medium-speed diesel engine. One of the main part of air starting motors is the axial turbine stage. In this study, design of 1-stage axial type turbine for 14kw class air starter motors has been performed. The turbine blade was designed based on mean-line analysis. 1-D design calculation and numerical analysis with CFD were conducted iteratively. The validation between 1-D design method and numerical analysis for axial clearance has been performed. It revealed that there is optimum axial clearance of turbine design.
