Enskog s dense gas theory for rigid spheres is also used as basis developing granular flow models. The modifications suggested extending the dense gas kinetic theory to particulate flows are discussed in chap 4. [Pg.324]

The two-fluid granular flow model is formulated applying the classical Eulerian continuum concept for the continuous phase, while the governing equations of the particle phase are developed in accordance with the principles of kinetic theory. In this theory it is postulated that the particulate system can be represented considering a collection of identical, smooth, rigid spheres, adapting a Boltzmann type of equation. This microscopic balance describes the rate of change of the distribution function with respect to position and time. [Pg.508]

Several early and recent investigators have derived variations of the throughput, axial velocity, and residence time expressions (Hogg et al., 1973 Perron and Bui, 1990) but Seaman s expressions given here have found most practical applications and are recommended for use in industrial kilns so long as there are no true granular flow models to predict the bed behavior as are available for fluids of isotropic materials. [Pg.28]

It should be recalled that, although a constant value of the solids concentration had been employed in the granular flow model. Equation (5.16) provides a means of determining changes in void fraction... [Pg.113]

Step algorithm was employed for the solution of an unsteady two-fluid granular flow model [136], The latter semi-implicit procedure has also been extended in order to simulate reactive flows in fluidized beds [138],... [Pg.1171]
