Numerical techniques play an important role in CFD.Some of themare reviewed in this paper.The necessity of using high order difference scheme isdemonstrated for
We present an adaptive lattice Boltzmann model to simulate super-sonic flows.The particle velocities are determined by the mean velocity and internalenergy.The
A theory of tailing wavetrain generation for the precursor solitongeneration in two-layer flow is presented by using averaged KdV equations(AKdV),which are deri
The performance of combustion driver ignited by multi-spark plugsdistributed along axial direction has been analysed and tested. An improved ignitionmethod with
The turbulence structures near a sheared air-water interface wereexperimentally investigated with the hydrogen bubble visualization technique. Sur-face shear wa
Coherent structures of a turbulent boundary layer were investigatedby hydrogen bubble method.A kind of fast changing structure was observed.Thatis a spot in whi
Experimental results on the instability of the isothermal natural-convection boundary layer around a vertical heated flat plate are presented.It isdemonstrated
In this paper,the supersonic chemically reacting mixing layer issimulated with the third order ENN scheme,based on the Navier-Stokes equations,containing transp
