In the bottom section, solids travel upwards in the outer annulus, and move down in the bed centre.
In the top section, solids travel upwards at the centre of the bed to the splash zone and then return to the intermediate height of the bed via the outer annulus.
Results showed that at high superficial gas velocities, especially in the turbulent regime, the cross section solids holdup exhibited a radially symmetric distribution, which was not the case for the bubbling regime.
Put him in power, and crime would be halved in 100 days.In this section Solid, but for how long?
But the subsequent investigation was remarkably sloppy; the closed trial of the alleged bombers now under way in Stavropol, in the south, raises many doubts.In this section Solid, but for how long?
It is certainly conceivable, so long as the generals and judges hold off, that he and his new Justice and Development party, better known by its initials AK, could be running Turkey in the not-too-distant future.In this section Solid, but for how long?
Although Colin Powell, America's secretary of state, is widely seen as a voice of moderation and caution, there is anxiety in some quarters of Europe about the instincts of Donald Rumsfeld and the Pentagon.In this section Solid, but for how long?
French ministers and officials point out that, although Article 5 of the NATO treaty, invoked for the first time ever in response to the terrorist attacks, states that an attack on one member is an attack on all, national governments still retain the right to decide how they should respond.In this section Solid, but for how long?
The models for the average solid holdup, the axial average section solid holdup and the bed expansion coefficient were developed.
(2) The axial average section solid holdup decreases with increasing bed height and increasing superficial gas velocity.
Correlations of average solid holdup, axial average section solid holdup and bed expansion coefficient were proposed based on the analysis of experimental data and previous studies.
