Heat convection characteristic in LNG storage tank when LNG stratification and rollover

Liquefied Natural Gas(LNG) is a kind of high quality and clean energy,but many accidents have taken places since it was widely used,and stratification is the necessary condition for rollover.

As the model takes no account of the consequences of boil off rate on density difference and can not interpret the acceleration of the interface's descending before rollover, the paper developed an advanced model which has 4 phases instead of 3 of the old one, and this phase dividing is more reasonable.

The Design Conception and Realization of Pulsatile Ventricular Assist Devices--From Spiral-Vortex Pump to Luo-Ye Pump;

Research on vortexes of cross flow past a horizontal circular cylinder by PIV system;

When the gas enters the stack by tangent and forms vortex,the negative pressure is formed in center of the flow field.

Dynamics of eddy-induced Kuroshio variability in Luzon Strait;

The simulated results are as follow:the mixture of gas-liquid two-phase can become more sufficient as adding the jet velocity of gas and the immerged depth of jet pipe,and the eddy forms more easily,the time of obtaining steady flow field is shortened.

An Arctic Ocean eddy in subsurface layer is analyzed in this paper with temperature, salinity and current profile data obtained at an ice camp in the Canada Basin during the second Chinese Arctic Expedition in summer of 2003.

Main advances of research on vortices in pump sumps;

Based on flow field analysis,it shows that owing to the wakes behind the upstream suction pipe,the downstream flow becomes more turbulent and appears with obvious free-surface vortices and submerged vortices in complicated movement.

The vortices flow in the blade passages and the influence of the eccentric inlet of the multi-blade centrifugal fan for air-conditioner have been analyzed numerically by using commercial CFD code.
