Injection을 갖는 Seal내의 난류유동에 관한 수치적 연구

A numerical analysis is performed on the incompressible turbulent flow in the seal with injection. The parameters used in this study are as follows: rotation speed, injection speed, clearance ratio, injection angle and injection location. Flow pattern and pressure drop due to the variation of parameter is investigated. SIMPLER algorithm is employed to solve the appropriate governing equation and standard k-e turbulent model is introduced.
