EFFECT OF SUSPENDED SOLID PARTICLES ON UNSTABILITY OF 2-DIMENSION MIXING LAYER

By considering the effect of suspended solid particles in the ordinary equations for two-dimension inviscid incompressible mixing layer, the Rayleigh equation and the modified Rayleigh equation are obtained. An d then, by solving the corresponding eigen-value equations with numeri cal computational method, the relation curves between perturbation fre quency and spacial growth rate of the mixing layer for the varying par ticle loading, ratio of particle velocity to fluid velocity and Stokes number are got. Sever al important conclusions on the effect of suspe nded solid particles on unstability of the mixing layer are presented in the end by analyzing all the relation curves.
