초록
Recently, car industry trend is downsizing, a lean-burn engine, green car and cost cutting. A turbocharger is the key components to improve fuel efficiency and power. This research is to study on the flow analysis in the performance analysis for change rotating speed of turbocharger turbine with three different rotating speed in the turbine. After measuring real design features, modeling, velocity distribution, pressure distribution and temperature distribution are conducted numerically. Torque and power are compared with three different cases in order to analyze the performance for turbine. Finally, optimum power is determined with the sequence of case 1, case 2, and case 3.
