Efficient Pneumatic Conveying Dense Phase vs. Dilute Phase ...
dilute phase pneumatic conveying as a rule. The first hurdle to meet with this mindset is to actually define dilute phas e. A widely accepted definition available for dilute phase flow is a two phase flow where all of the conveyed particles are carried in suspension [1]. From a practi cal standpoint this definition is useless

Simulations of Dense-phase Pneumatic Conveying
matic conveying: dilute and dense phase con-veying. Dilute phase conveying has been stud-ied in much detail, but not dense phase convey-ing. Analysis of the latter is difficult, because particle interaction is important. One observes particle density waves that are difficult to treat with simple models. Dense-phase conveying can be further subdi-

Dilute phase vs. dense phase pneumatic conveying: What's ...
For dilute phase conveying, a relatively high conveying air velocity must be maintained. The typical velocity of dilute phase systems is in the range of 5,000 ft./min. to 8,000 ft./min. It’s not a constant velocity, though; there’s a pick-up velocity at the beginning of the conveying and a terminal velocity at the end, as well as ...
