Dear Sirs,

I'm sorry to see that the dynamic of discussions here has came to an almost silent state.

I have something unclear and i would kindly ask for your opinion on it. And i'm referring to pneumatic conveying, in vacuum, of course dilute phase.

There is a parameter called Clogging constant. And this parameter is related to the clogging regime mixing ratio, to the Froude criteria and also to the cross section area of the pipe. For the definition of this Clogging regime mixing ratio there are some formulas that does not take into account the nature of product but only the dynamic of the regime and they are actually deducted by regression .

I suppose that the clogging regime mixing ratio is also directly related to the pressure gradient.

And i suppose there is direct multiplication with the value of the absolute pressure gradient with the clogging constant, cross section area and Fr^2.

Do you have any information or experience about it ?

Thank you very much for your valuable help and your time.

Sincerely yours,

Tanase TANASE
