Rocky module Parametric Gidaspow, parameter value clarification

[seijieng]

In the Parametric Gidaspow, Bezburuah & Ding Module, parameter P3's default value is 2.333 (=7/3) instead of 7. Equation 34-3 shows the factor of 3 still in the denominator. Should the default value for P3 be 7 instead?

34-2

 

34-3

Hi Seijieng,

The equations 34-2 and 34-3 are derived from equation (3.41) of Chapter 3.2.3.3 (Gidaspow, Bezburuah & Ding, 1992) of the Rocky CFD Coupling Technical Manual. The correct value for P3 is 2.333 (7/3), and the second equation should be corrected to P3/Φ.

Thank you for pointing this out; we will ensure this correction is made.

Best regards,
