Optimum Design of the Air-turbine for the High-speed Dental Air-turbine Handpiece Using Design of Experiment
High-pressure air enters the air-turbine of the dental handpiece and strikes the blades to drive the impeller. The air-turbine has impeller and the air tube is connected to the air-turbine housing. The flowfield of the air-turbine were investigated for the optimum air-turbine design using ANSYS CFX. The objective of the research was to find an optimum design variables for the air-turbine to inc...
متن کاملBacteriological evaluation of a new air turbine handpiece for preventing cross-contamination in dental procedures.
An autoclavable air turbine handpiece, Air Flushing Clean System (AFCS) (Osada Electric Co., Ltd., Tokyo, Japan) was developed for use in dentistry with the objective of reducing cross-contamination. Its potential for bacterial contamination was investigated in vitro using two bacterial strains (Streptococcus mutants ATCC 25175 and Staphylococcus aureus FDA 209 P). In theory, this device should...
متن کاملComputational Approach to Design the High-speed Dental Air-turbine Handpiece
The high-speed dental air-turbine handpieces are widely used in the dentistry as a tool for cutting and drilling a tooth. The advanced existing high-speed dental air-turbine handpieces were investigated to design the high performance dental air-turbine handpiece. The coupler and air-turbine of the dental air-turbine handpiece was designed using computational analysis. The computational domain o...
متن کاملPerformance study of a renewable fuel-fed micro humid air turbine
Biogas is a proven and valuable energy source today for combined production of heat and electricity (CHP). In this paper, a novel CHP system installation based on a 500 kW micro humid air turbine (mHAT) in a wastewater treatment plant (WWTP) is presented and discussed. Furthermore, some considerations regarding an appropriate biogas treatment system and heat recovery module is discussed. The re...
