Distribution Of Gas Flow Shape Inside Rotary Kiln Tube

CFD-code PHOENICS. The results indicate that the gas flow and mixing inside the kiln is very complicated. The 3-dimensional gas flow will help to better understand the heterogeneous temperature distribution inside the kiln, which will affect significantly the bed behaviour and refractory lining wear. In the future, heat transfer within the.
