CFD approach for the moisture prediction in spray chamber for drying of salt solution
چکیده انگلیسی

This investigation describes and demonstrates the effectiveness of computational fluid dynamics, CFD, method to predict the moisture changes during drying process of salt solution in co-current spray dryer. In order to prove the validity of predicted profiles, the obtained results were compared by reported experimental data. The moisture profile calculated by two dimensions model confirmed the sharp change in moisture pattern close to the center of drying chamber. It is proven that the moisture reaches to constant value as radial distance increases up to 20%. The model was also employed to investigate the influence of operating parameters such as, salt concentration, feed rate, hot air flow rate and temperature, inlet air moisture, and outlet suction pressure on moisture distribution. It was found that the feed rate and suction pressure significantly affect the moisture profile in radial and axial directions. The obtain results can be used in industrial practice.
