Analytical solutions for the interfacial viscous capillary-gravity waves due to an oscillating Stokeslet被引量:1
《Journal of Hydrodynamics》2019年第6期1139-1147,共9页Dong-qiang Lu 
Project supported by the National Natural Science Foundation of China(Grant Nos.11872239,10602032).
The fundamental solutions of the Stokes/Oseen equations due to a point force in an unbounded viscous fluid are referred to as the Stokeslet/Oseenlet,for which a systematic derivation are analytically presented here in...

SURFACE AND INTERFACIAL GRAVITY WAVES INDUCED BY AN IMPULSIVE DISTURBANCE IN A TWO-LAYER INVISCID FLUID被引量:3
《Journal of Hydrodynamics》2009年第1期26-33,共8页LU Dong-qiang CHEN Ting-ting 
Project supported by the National Natural Science Foundation of China (Grant No 10602032);the Shanghai Rising-Star Program (Grant No 07QA14022)
The transient gravity waves due to an impulsive source in a two-layer fluid system are investigated analytically. The fluid is assumed to be inviscid and incompressible. The density of each of the two layers is consta...
