Competition of the multiple Grtler modes in hypersonic boundary layer flows被引量：6
《Science China(Physics,Mechanics & Astronomy)》2014年第6期1178-1193,共16页REN Jie FU Song 
supported by the National Natural Science Foundation of China(Grant Nos.10932005 and 11202115)
Competition of multiple Gortler modes in hypersonic boundary layer flows are investigated with the local and marching methods. The wall-layer mode （mode W） and the trapped-layer mode （mode T） both occur in the com...

Floquet analysis of fundamental,subharmonic and detuned secondary instabilities of Grtler vortices被引量：3
《Science China(Physics,Mechanics & Astronomy)》2014年第3期555-561,共7页REN Jie FU Song 
supported by the National Natural Science Foundation of China(Grant Nos.10932005 and 11202115)
Nonlinear parabolized stability equations are employed in this work to investigate the nonlinear development of the G6rtler insta- bility up to the saturation stage. The perturbed boundary layer is highly inflectional...

Numerical investigation of the casing treatment mechanism with a single circumferential groove被引量：1
《Science China(Physics,Mechanics & Astronomy)》2013年第2期353-365,共13页SHI Ke CHEN HaiXin FU Song 
supported by the GE Aviation under its University Strategic Alliance(USA) program;supported by the National Natural Science Foundation of China(Grant Nos.10932005 and 11272183)
The paper investigates the effect of a single circumferential groove casing treatment(CGCT) on a transonic compressor rotor numerically.In particular,the effect of the groove at different axial locations on the flow f...

A Karman-Vortex Generator for passive separation control in a conical diffuser被引量：7
《Science China(Physics,Mechanics & Astronomy)》2012年第5期828-836,共9页ZHANG YuFei CHEN HaiXin FU Song 
supported by the National Natural Science Foundation of China (Grant Nos.10932005,10972120 and 11102098);the China Postdoctoral Science Foundation (Grant No.2011M500301)
Flow separation in a conical diffuser with large divergence angle （29.14°） and large area ratio （3.533） is eliminated by a novel passive flow control device called Karman-Vortex Generator （KVG）. The effect of t...

Drag reduction of compressible wall turbulence with active dimples被引量：3
《Science China(Physics,Mechanics & Astronomy)》2011年第2期329-337,共9页SUN ZhenSheng REN YuXin LARRICQ Cedric 
supported by the National Natural Science Foundation of China (Grant Nos.10932005 and 50910222)
Direct numerical simulations are carried out to assess the potential drag reduction of compressible turbulent flow between isothermal walls.For the sake of achieving drag reduction,the flow is actively controlled by d...
