Pressure drop calculation for dense phase pneumatic conveying system.

Posted in: , on 11. Mar. 2017 - 16:17

Hello expert,

As a part of my study project i stuck in some calculation. My project is "Pressure drop prediction in dense phase pneumatic conveying system for foundry sand"

I want to know that

With which numerical method i can calculate pressure drop in dense phase system.?

( Can Bernoulli's Equation work for this system ?)

If Bernoulli equation work for this system how to implement air and sand both density in single equation?

Here i am attaching my experimental setup.

Attachment 45395

Your single suggestion will be precious for me.

Thanking you,

Dear absharma1892,

Ask Mr. Agarwal for a copy of his article [b/]Design Calculations for Pneumatic Conveying[/b].

In your sketch, a filter on top of the silo is missing.

Combining the velocity and the pipe diameter gives you the compressor size.

At a compressor pressure of 5 barg (which seems very high), the velocity is certainly not constant along the pipeline, due to air expansion.

As the conveying distance is very short, the pressure drop for acceleration and material resistance will consume a big portion of the total pressure drop.

A mechanical system could be a better solution, considering the short distance.

Take care

Teus

Thank you Mr. Teus for your cooperation.

yes, i will make it correct and reduce pressure in my experimental setup.

&

Actually Mr.Agarwal's articles is for dilute phase system. and my project is based on dense phase system.

If you or any Expert have any articles related to calculation of dense phase system, pls send me by mail.

Thanking you,

Thank you Mr.Teus for your cooperation.

&

I will make it correct and reduce the inlet pressure.

Mr. Agarwal's article is for Dilute phase and my project is on Dense phase pneumatic conveying.

If you have or any other Expert have articles for Dense phase pneumatic conveying, pls send me by mail.

Thanking you,
