Dear all
I would like to know if for two-phase solid-gas flow in dusty regime (dusty regime consider the flow as a single phase flow where particle fellow the flow streams), the pressure drop can be calculated using the correlation of single phase flow or should use the correlations for two phase flow ? any suggestions for the appropriate correlation ? Regards
For small size particles, it is expected that the particles will be uniformly distributed and hence if volume fraction of particles is known you can compute mixture density and viscosity. Once this information is known you can use single phase correlations.
Prof. Rakesh and Dr. Alexander, thank you for your interesting feedback
Regards
As you is working with a one- way coupling approach, the particles does not have influence on the fluid flow field as you postulated. And based on this, the flow field of fluid is 'blind' regarding the particles velocities distribution. And so do doing, the pressure drop is function of the velocity field of the fluid with a weak coupling with the volume fraction of dust - considering a low void fraction. Of course, the mixture properties can be accounted for as pointed out by Mishra and Chernyshev.
