Detailed Description

H, Enwald, E. Peirano, A-E Almstedt 'Eulerian Two-Phase Flow Theory Applied to Fluidization' Int. J. Multiphase Flow, Vol. 22, Suppl, pp. 21-66 (1996) Eq. 86-87, p. 40.

This is identical to the Wen and Yu, Rowe model Table 3.6 p.56 in the Ph.D. thesis of Berend van Wachem 'Derivation, Implementation and Validation of Computer Simulation Models for Gas-Solid Fluidized Beds'

NB: The difference between the Gidaspow-version is the void-fraction in the Re-number

The drag function K used in the momentum eq.

ddt(alpha1*rho1*U1) + ... = ... alpha1*alpha2*K*(U1-U2) ddt(alpha2*rho2*U2) + ... = ... alpha1*alpha2*K*(U2-U1) NB! ***************************** for numerical reasons alpha1 and alpha2 has been extracted from the dragFunction K, so you MUST divide K by alpha1*alpha2 when implementing the drag function NB! *****************************

Implements dragModel.
