Recently, car industry adopted a turbo charger to cope with the "Euro 6.’ it is crucial to have turbo charger in order to improve fuel efficiency and solve exhaust gas problem. In this research, according to the turbin"s RPM transition of VGT turbo charger, we investigated a flow analysis. According to the turbine RPM change, we compared velocity distribution, pressure distribution and temperature distribution As efficiencis of each case are compared based on PRM changes, case 1, 72.75%, proved to be most efficient while case 2 and 3 showed 65.74% and 52.95% respectively.
