]]>The shock wave structure of a binary mixture with very different molecular weights is analyzed using a two-fluid theory in the limit of small Prandtl ($\text{Pr}$) number of the light gas. In particular, the case in which both the density ratio and $\mathrm{\Lambda}=\text{Pr}/\delta \text{Sc}$ are order unity or below is considered, where $\delta \ll 1$ i…

The bubble is assumed to undergo volume and translational oscillations. The volume oscillation is caused by an imposed acoustic pressure field and g…

We study elastic fingering pattern formation in Newtonian fluids flowing in a lifting (time-dependent gap) Hele-Shaw cell. Using a…
