A. Bird The quantum-kinetic, or Q-K, model is based on the quantum vibration model that is employed in the computation of gas flows at the molecular level by the direct simulation Monte Carlo (DSMC) method. The Q-K procedure for dissociation is physically realistic within the context of the vibration model ... [Phys. Fluids 23, 106101 (2011)] published Fri Oct 21, 2011.

Abrahamsen and Odd M. Faltinsen The phenomenon studied in this work is that of an air pocket entrapped by a free surface water wave inside a rectangular tank at a high filling level. The wave, which is a gravity wave, is caused by forced horizontal motion which is constructed in a particular way, in order to entrap an air pocket a ... [Phys.

Fayzrakhmanova, Arthur V. Straube, and Sergey Shklyaev We consider a sessile hemispherical bubble sitting on the transversally oscillating bottom of a deep liquid layer and focus on the interplay of the compressibility of the bubble and the contact angle hysteresis. In the presence of contact angle hysteresis, the compressible bubble exhibits two kinds ... [Phys. Fluids 23, 102105 (2011)] published Wed Oct 19, 2011.

The jet then breaks into uniform drops charged at an approximately constant fraction of the Rayleigh limit, which relates the drop diameter D to the flow rate ... [Phys.
