An exact axisymmetric spiral solution of incompressible 3D Euler equations
Liang Sun
Spiral structure is one of the most common structures in the nature flows. A general steady spiral solution of incompressible inviscid axisymmetric flow was obtained analytically b…
General Temporal Instability Criteria For Stably Stratified Inviscid Flow
Liang Sun
The temporal instability of stably stratified flow was investigated by analyzing the Taylor-Goldstein equation theoretically. According to this analysis, the stable stratification…
Stabilities of Parallel Flow and Horizontal Convection
Liang Sun
In the first part, the stability of two-dimensional parallel flow is discussed. A more restrictively general stability criterion for inviscid parallel flow is obtained analytically…
Onset of unsteady horizontal convection in rectangle tank at
Liang Sun, Dong-Jun MA, Wei Zhang +1
The horizontal convection within a rectangle tank is numerically simulated. The flow is found to be unsteady at high Rayleigh numbers. There is a Hopf bifurcation of from stea…
Essence of inviscid shear instability: a point view of vortex dynamics
Liang Sun
The essence of shear instability is fully revealed both mathematically and physically. A general sufficient and necessary stable criterion is obtained analytically within linear co…
General stability criteria for inviscid rotating flow
Liang Sun
The general stability criteria of inviscid Taylor-Couette flows with angular velocity are obtained analytically. First, a necessary instability criterion for centrifugal flo…
