Numerical investigation of clocking in a two-stage gas turbine
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 ...
متن کاملconceptual design of a centrifugal compressor impeller for a 65 kw micro gas turbine
the aim of this study is designing the impeller of a centrifugal compressor in order to supply pressure ratio for a 65 kw micro gas turbine. first, the primary thermodynamic analysis has been conducted for the considered cycle using a home made code. herein, the compressor pressure ratio was considered to be 4. the obtained thermal efficiency was 25.64%. then, the design of micro compressor in ...

متن کاملNumerical Investigation of Rotating-Stall in a Stage of an Axial Compressor with Two Different Approaches
An unsteady two-dimensional finite-volume solver was developed based on Van Leer’s flux splitting algorithm in conjunction with “Monotonic Upstream Scheme for Conservation Laws (MUSCL)” limiters and the two-layer Baldwin-Lomax turbulence model was also implemented. To validate the solver, two test cases were prepared and the computed results had good agreements with reference data. The rotating...
