Numerical simulation of liquid sloshing in a partially filled container with inclusion of compressibility effectsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Y. G. Chen and W. G. Price A numerical scheme of study is developed to model compressible two-fluid flows simulating liquid sloshing in a partially filled tank. For a two-fluid system separated by an interface as in the case of sloshing, not only a Mach-uniform scheme is required but also an effective way to eliminate unphysi ... [Phys.

Large eddy simulation (LES), in which the large scales of turbulence are simulated while the effects of the small scales are modeled, is an attractive approach for predicting the behavior of turbulent flows. However, there are a number of modeling and formulation challenges that need to be addressed ... [Phys. Fluids 21, 105104 (2009)] published Fri Oct 23, 2009. (Source: Physics of Fluids)

Coating flow of viscous Newtonian liquids on a rotating vertical diskEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Nilesh H. Parmar, Mahesh S. Tirumkudulu, and E. J. Hinch We study a Newtonian viscous liquid coating a vertical rotating disk in the creeping flow regime. Experiments were performed at varying disk rotation speeds and liquid volumes, and the thickness profile at steady state was measured. While the maximum liquid supported by the rotating disk varied with ... [Phys. Fluids 21, 103102 (2009)] published Thu Oct 22, 2009. (Source: Physics of Fluids)

Lattice Boltzmann simulation of the rise and dissolution of two-dimensional immiscible dropletsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Cheng Chen and Dongxiao Zhang We used a coupled multiphase lattice Boltzmann (LB) model to simulate the dissolution of immiscible liquid droplets in another liquid during the rising process resulting from buoyancy. It was found that there existed a terminal rise velocity for each droplet, and there was a power law relationship b ... [Phys. Fluids 21, 103301 (2009)] published Thu Oct 22, 2009.

Effects of geometric shape on the hydrodynamics of a self-propelled flapping foilEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Xing Zhang, Saizhen Ni, Shizhao Wang, and Guowei He The hydrodynamics of a free flapping foil is studied numerically. The foil undergoes a forced vertical oscillation and is free to move horizontally. The effect of chord-thickness ratio is investigated by varying this parameter while fixing other ones such as the Reynolds number, the density ratio, a ... [Phys.

Purely analytic solutions of the compressible boundary layer flow due to a porous rotating disk with heat transferEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
M. Turkyilmazoglu The motivation of the present study is to obtain exact analytical solution of the steady laminar flow of a compressible viscous fluid over a rotating disk subjected to a uniformly applied suction or blowing. Classical Von Karman problem of a rotating disk is extended to account for the compressibili ... [Phys. Fluids 21, 106104 (2009)] published Wed Oct 21, 2009. (Source: Physics of Fluids)

Nucleation threshold and deactivation mechanisms of nanoscopic cavitation nucleiEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Bram M. Borkent, Stephan Gekle, Andrea Prosperetti, and Detlef Lohse The acoustic nucleation threshold for bubbles trapped in cavities has theoretically been predicted within the crevice theory by Atchley and Prosperetti [The crevice model of bubble nucleation, J. Acoust. Soc. Am. 86, 1065 (1989)]. Here, we determine this threshold experimentally, by applying a singl ... [Phys. Fluids 21, 102003 (2009)] published Mon Oct 19, 2009. (Source: Physics of Fluids)
