TY - JOUR ID - TI - Computer Aided Design for Spray Driers AU - Adil A. Al-Hemiri عادل احمد الحميري AU - Saad N. Saleh PY - 2007 VL - 8 IS - 1 SP - 27 EP - 34 JO - Iraqi Journal of Chemical and Petroleum Engineering المجلة العراقية للهندسة الكيمياوية وهندسة النفط SN - 19974884 26180707 AB - The aim of this work is to develop an axi-symmetric two dimensional model based on a coupled simplified Computational Fluid Dynamic (CFD) and Lagrangian method to predict the air flow patterns and drying of particles. Then using this predictive tool to design more efficient spray dryers. The approach to this is to model what particles experience in the drying chamber with respect to air temperature and humidity. These histories can be obtained by combining the particles' trajectories with the air temperature / humidity pattern in the spray dryer. Results are presented and discussed in terms of the air velocity, temperature, and humidity profiles within the chambers and compared for drying of a 42.5% solids solution in a spray chamber 2.22 m in diameter with a cylindrical top section 2.00 m high and a bottom cone section 1.725 m high.
