Linear stability of channel flow with microgroove-type anisotropic superhydrophobic walls
Xueyan Zhai, Kaiwen Chen, Baofang Song
We study the temporal linear instability of channel flow subject to a tensorial slip boundary condition that models the slip effect induced by microgroove-type super-hydrophobic su…

Cancellation exponents in isotropic turbulence and magnetohydrodynamic turbulence
X. M. Zhai, K. R. Sreenivasan, P. K. Yeung
Small scale characteristics of turbulence such as velocity gradients and vorticity fluctuate rapidly in magnitude and oscillate in sign. Much work exists on the characterization of…
