simulation of rotary cement kilns using a one-dimensional

Mar 01, 2006 In recent years, computational fluid dynamics (CFD) based models are being applied to simulate rotary kilns (Mastorakos et al., 1999; Ranade, 2003). It is possible to simulate coal burner and free board region of rotary kiln fairly accurately using the state of the art CFD models (Mastorakos et al., 1999; Karki et al., 2000; Ranade, 2003)
