Flow in the first two-stage of V 94.2 gas turbine is simulated numerically. In this turbine, the second stator is clocked relative to the first stator to different positions. Steady-state analysis was carried out by varying the circumferential relative position of the consecutive stator vanes to study the effects of the clocking on turbine performance. A density based compressible inviscid flow (Euler equations) solver is used for the flow simulation. The efficiency analysis and entropy generation investigation are performed and the appropriate position of the second stator is obtained. The attained efficiency improvement matches the results obtained by the entropy generation analysis.
