Liutex based new fluid kinematics被引量：3
《Journal of Hydrodynamics》2022年第3期355-371,共17页Chaoqun Liu Yifei Yu Yi-sheng Gao 
The authors are thankful for the support by the UTA Department of Mathematics which houses the UTA Vortex and Turbulence Research Team.The authors are also grateful to Texas Advanced Computing Center(TACC)for providing computation time.The DNSUTA code was released by Chaoqun Liu in 2009 and the Liutex code was released by Chaoqun Liu in 2018 which can be downloaded from the UTA web site at https://www.uta.edu/math/cnsm/public_html/cnsm/cnsm.html.
The traditional Cauchy-Stokes(C-S)decomposition states that the velocity gradient tensor can be decomposed into a symmetric tensor and an anti-symmetric tensor,namely the strain-rate tensor and the vorticity tensor.Ho...

NUMERICAL ANALYSIS OF THE FLUID FLOW IN A ROTATING CURVED ELLIPTICAL PIPE被引量：2
《Journal of Hydrodynamics》2005年第2期171-178,共8页MAJian-feng SHENXin-rong ZHANGBen-zhao CHENHua-jun 
the National Natural Science Foundation of China(Grant No: 10272096)
A numerical study was conducted for the fully developed laminar flow in rotating curved elliptical pipe. Due to the rotation, the Coriolis force can also contribute to the secondary flow. The interaction of rotation a...
