Abstract

In order to find out the correspond relationship of the outlet velocity and rotor speed in dry powder inhaler, the intermediate parameter was inserted in Workbench response surface based on CFD. The simulation of the suction drive rotor rotation mechanism was based on MRF model in FLUENT. It can be easily obtained the rotor’s performance curve under different aerodynamic conditions and found out the optimized flow rate is 66.127L/min. This method verifies the clinical phenomena and could guide the clinical research and machinery optimization.
