Numerical Study of a Gas Bubble Rising Through Stagnant Fluid

It is well known that the environment degradation has come along the time positioning as one of the main problems from modern world. Among several questions of the environmental interest the methane bubble rise in the lakes can be emphasized, from the anoxic sediment in the bottom of lake until water interface atmosphere. In particular, the present academic work has come to treat mathematic mod...

Cerebrospinal fluid: a rising subject in brain development

Many research studies in developmental neurosciences have been focused on neuroepithelial cellular events at the tissue, cellular, and molecular levels, in order to understand how the brain develops from a single structure, the neural tube. Although a couple of researchers (such as Mary Desmond, from Villanova University as an outstanding figure) introduced the idea that the cavity of the neura...

Simulation of a cusped bubble rising in a viscoelastic fluid with a new numerical method

We developed a new lattice Boltzmann method that allows the simulation of two-phase flow of viscoelastic liquid mixtures. We used this new method to simulate a bubble rising in a viscoelastic fluid and were able to reproduce the experimentally observed cusp at the trailing end of the bubble.  2000 Elsevier Science B.V.

On the stability of gas bubbles rising in an inviscid fluid

Rising Star

W hat a great stroke of luck this winter for the National Basketball Association (NBA). After the walkout of 2011 that featured multimillionaires arguing with billionaires over their fair share of the league revenues, when most sports fans could not be coaxed away for the National Football League playoff games and the National Hockey League, enter phenom Jeremy Lin to save the face of the NBA. ...
