摘要:
针对含表面活性剂表面下方浸没物体脉冲运动产生的瞬态自由表面波与Marangoni波,本文建立了粘性流体中的Oseen问题。采用Lighthill两阶段方案,求得了大Reynolds数下的波渐近性与波前。所得结果明确揭示了粘性与表面活性剂对Kelvin尾迹的影响。
英文摘要:
The Oseen problem in a viscous fluid is formulated for studying the transient free-surface and Marangoni waves generated by the impulsive motion of a submerged body beneath a surface with surfactants. Wave asymptotics and wavefronts for large Reynolds numbers are obtained by employing the Lighthill's two-stage scheme. The results obtained show explicitly the effects of viscosity and surfactants on the Kelvin wakes.
