Abstract: Computational fluid dynamics models are developed to investigate the airflow induced by cutting blades used in a lawn care cutting pan. The effects of blade profiles on mass flow rates and power consumptions are investigated thoroughly through the computer models. The simulation results are useful for designing the blade profiles that produce desired mass flow rate of air at minimal power. Experiments were carried out to validate the simulation results obtained using the computational models.
