摘要: This paper presents a CFD study of short and tall spray dryers. The simulations were performed using turbulent model; standard k-e (SKE), realizable (RKE) the Detached Eddy Simulation (DES). predicted axial velocity, temperature humidity profile inside drying chamber found to be in fair agreement experimental data adapted from literature for model tested this work. provides more accurate prediction fluid flow co-current dryer. Moreover, particle tracking has been included source-in-cell method enable calculation residence time (RTD) their impact positions chamber. suggests that dryer less overall than shorter one due lesser recirculation.
