$H$-theorem and boundary conditions for two-temperature model: Application to wave propagation and heat transfer in polyatomic gases
Author(s): Anil Kumar and Anirudh Singh Rana
Polyatomic gases find numerous applications across various scientific and technological fields, necessitating a quantitative understanding of their behavior in nonequilibrium conditions. In this study, we investigate the behavior of rarefied polyatomic gases, particularly focusing on heat transfer a…

Dynamics of a silicone oil drop submerged in a stratified ethanol-water bath
Author(s): Miguel A. Herrada, José M. Montanero, and Luis Carrión
We analyze numerically the Marangoni flow around an immiscible droplet submerged in a stably stratified mixture of ethanol and water. The linear stability analysis shows that the base flow undergoes a supercritical Hopf bifurcation that leads to oscillations. The theoretical prediction for the criti…
