摘要

In the first year of our investigation we have focused on interfacial instabilities in two-layer Poiseuille flow. Initially we have neglected temperature and viscosity fluctuations. In the second year of our investigation we have incorporated the effects of temperature and viscosity fluctuations in our analysis. The results indicate that temperature and viscosity perturbations have a pronounced effect on the interfacial mode of instability. This is in contrast to our findings on the stability of plane, single-layer, Poiseuille flow for liquids exhibiting exponential viscosity-temperature dependence.
