	1	Turbulent lock release gravity current显示文摘The time evolution of a turbulent lock release gravity current, formed by a finite volume ofhomogeneous fluid released instantaneously into another fluid of slightly lower density, was studied byexperimental measurements of the density structure via elaborate digital image processing and by a nu-merical simulation of the flow and mixing using a two-equation turbulence model. The essential fact thatthe gravity current passes through an initial slumping phase in which the current head advances steadilyand a second self-similar phase in which the front velocity decreases like the negative third power of thetime after release is satisfactorily presented by the laboratory observation. An overall entrainment ratioproportional to the distance from the release point is found by the numerical simulation. The renormal-ization group (RNG) k- ε model for Reynolds-stress closure is validated to characterize the gravitycurrent with transitional and localized turbulence.	陈国谦 Joseph H.w.Lee	2001	Science China(Technological Sciences)2001，44，5：	1
	2	ZAKHAROV EQUATION FOR SURFACE GRAVITY WAVES IN SHEAR FLOW显示文摘The fourth-order Zakharov integral equation for surface gravity waves derived by Stiasshie and Shemer is modified to include the effect of shear flow. Using this new equation the class instability of a Stokes wave train in shear flow is studied. The effect of the vorticity on the instability is discussed, and a kind of new unstable regions has been found.	周清甫 Y.K.CHEUNG JOSEPH H.W.LEE	1990	Science China Mathematics1990，33，10：	0
