A numerical simulation of a gas-fluidized bed is performed without introduction of any empirical parameters. Realistic bubbles and slugs are observed in our simulation. It is found that the convective motion of particles is important for the bubbling phase and there is no convection in the slugging phase. From the simulation results, non-Gaussian distributions are found in the particle velociti...

A suitable initial point for understanding multiphase flows is a phenomenological description of the mechanism geometric distributions or flow patterns that are observed. The challenge however prediction combination operating conditions and characteristics phases as well points transition from one pattern to other. Different occur in different pipeline configurations which U-shape risers part. ...

This pape,r describes a flow-visualizatio n technique that was employed to qualitatively evaluate the gas flow pattern inside a small, low side, hermetically sealed, re ciprocating refrigeration compressor. The applicable compressor des igns are those in which the suction gas from the evaporator is dumped into the compressor shell, and is then drawn through a muffler into the suction plenum of ...

Are the associations between the facial width-to-height ratio (fWHR) and Japa-nese male baseball player performance documented by Tsujimura & Banissy [1] robust to controlling for body mass index (BMI)? Two factors motivate this question. First, research suggests that BMI is positively associated with both home run hitting [2,3] and fWHR [4,5]. Second, recent research has suggested that body si...
