Abstract |
The high-speed dental handpieceair-turbine is widely used in cutting and polishing denture structure in dentistry. The impeller of the air-turbine is the important part of the dental handpiece. The objective of the study was to investigate the flowfield of the air-turbine with the gull type impeller and to find the design variables for the optimization. The flowfield of the air-turbine was computed usingANSYS Fluent Computational Fluid Dynamics (CFD) software. The airflow inside the air-turbine was analyzed by changing the height and number of the impeller blade and location of the air inlet. The computed results were evaluated by the velocity, pressure and the torque. The torque value was increased when the height of the blade and connecting location of the air-inlet are changed.
