Original Abstract

The aim of this study is to minimize minor losses in cap-end ports of a pneumatic cylinder used in pneumobil vehicle engine. Six geometry arrangements of intake ports,including the currently used version, were designed assuming conventional machining technology.Boundary conditions for the analysis were acquired from experimental measurement. The airflow was analyzed by 3D stationary CFD analysis in ANSYS Fluent for all designs. Pressuredrop was used as the evaluation criteria. Two best configurations according to the obtainedresults were optimized using ANSYS Fluent Adjoint Solver. The pressure drop was reducedby 81.1% using this method. The obtained results will be used for design of solid geometrycustomized for production by lost wax casting process.
