The effect of diffusive mass transfer on interfacial fluid instabilities

扩散传质对界面流体不稳定性的影响。各种各样的工业和生理流体流动属于两层流体的一般类别，其中一种密度/粘度的流体流过另一种不同密度/粘度的流体。这种流动最终可能会通过小的背景扰动的增长而变得混乱(即混乱)。对这一过程的理解对于控制流体动力混合具有重要意义。该项目将考虑扩散传质作用于流体界面时的两层流动，目的是确定扩散如何影响从过渡到湍流的过程。

The effect of diffusive mass transfer on interfacial fluid instabilities. A wide variety of industrial and physiological fluid flows fall into the general class of two-layer fluids wherein a fluid of one density/viscosity flows over another of a different density/viscosity. Such flows can ultimately become turbulent (that is, chaotic) through the growth of small background disturbances. An understanding of this process is important in controlling fluid dynamical mixing. This project will consider two layer flows in the case when diffusive mass transfer acts at the fluid interface with the aim of determining how diffusion affects the process of transition-to-turbulence.
