Laminarization of internal flows under the combined effect of strong curvature and rotation
Guleren, K. M.; Afgan, I.; Turan, A. (ASME, 2008)The laminarization phenomenon for the flow under the combined effect of strong curvature and rotation is discussed based on numerical predictions of large-eddy simulation (LES). Initially, the laminarization process is ... -
Large-eddy simulation of the flow in a low-speed centrifugal compressor
Guleren, K. M.; Turan, A.; Pinarbasi, A. (JOHN WILEY & SONS LTD, 2008)The results of a series of numerical simulations for the NASA low-speed centrifugal compressor are presented. Large-eddy simulation (LES) is carried out together with the most commonly used Reynolds-averaged Navier-Stokes ... -
Measurements of Reynolds stresses in centrifugal compressor vaned diffusers
Pinarbasi, A.; Guleren, K. M.; Ozturk, A. (PROFESSIONAL ENGINEERING PUBLISHING LTD, 2008)A phase lock loop sampling technique has been developed in order to perform detailed measurements for the flow field downstream of a turbomachinery rotor. Measurements have been carried out in the vaned diffuser of a ... -
Predictions of Turbulent Flow for the Impeller of a NASA Low-Speed Centrifugal Compressor
Guleren, K. M.; Afgan, I.; Turan, A. (ASME, 2010)The turbulent flow inside a low-speed centrifugal compressor at design condition is investigated using large-eddy simulation (LES) comprising of up to 26x10(6) computational volume cells. Unlike in the past, the current ... -
Validation of large-eddy simulation of strongly curved stationary and rotating U-duct flows
Guleren, K. M.; Turan, A. (ELSEVIER SCIENCE INC, 2007)Numerical predictions of the developing turbulent flow through stationary and rotating U-ducts with strong curvature are presented using large-eddy simulation (LES). The primary aim is to validate LES in a strongly curved ...
