A numerical and experimental investigation of the effects of flow ratio on the flow and performance characteristics of a twin entry radial turbine
, Article Proceedings of the ASME Turbo Expo, 6 June 2011 through 10 June 2011 ; Volume 7, Issue PARTS A, B, AND C , 2011 , Pages 2139-2153 ; 9780791854679 (ISBN) ; Hajilouy Benisi, A ; Rajabian, M ; Sharif University of Technology
Abstract
In this paper, a numerical and experimental investigation of the performance and internal flow field characteristics of the twin-entry radial inflow turbine under full and partial admission conditions are presented. The turbine is tested on a turbocharger test facility which was developed for small and medium size turbochargers. The flow pattern in the volute and impeller of a twin-entry turbine is analyzed using a fully three-dimensional viscous program. The computational performance results are compared with the experimental results, and good agreement is found. The flow field at the outlet of the turbine is investigated using a five-hole pressure probe. Numerical and experimental results...

Abstract
This paper presents numerical and experimental investigation of the performance and internal flow field characteristics of twin-entry radial inflow turbines at full and extreme partial admission conditions. The turbine is tested on a turbocharger test facility, which was developed for small and medium size turbochargers. Experimental results show that the lowest efficiency corresponds to extreme conditions. Therefore, flow field analyzing is employed to consider these conditions. The flow pattern in the volute and impeller of a twin-entry turbine is analyzed using an in-house fully three-dimensional viscous flow solver. The computational performance results are compared with the experimental...
