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 کاملPerformance of a Two-stages Gas Gun: Experimental, Analytical and Numerical Analysis
Two stages gas guns are used for various purposes, particularly for mechanical characterization of materials at high rate of deformations. The performance of a two stages gas gun is studied in this work using the theory of the two-stage gas gun proposed by Rajesh, numerical simulation using combined Eulerian/ Lagrangian elements in Autodyna commercial code and experiment using a two stage gas g...
متن کاملCarbon reservoirs on Mars: Constraints from Martian meteorites
Introduction: The search for life on Mars is a subject of enormous scientific and public interest; it is anticipated that remote missions to Mars over the coming few years will garner the requisite data that will allow the presence, or otherwise, of martian biological carbon to be determined. The only previous attempt to detect the presence of life in martian soil, made by instruments on the Vi...
متن کاملAtmospheric Thickness on Ancient Mars: Constraints from Snc Meteorites
Introduction: Mars atmospheric pCO2 levels between 4.5-3.8 Ga have commonly been estimated at 13 bar [1,2] based on the existence of fluvial features or sedimentary rocks on the surface of Mars. Most of the original atmospheric CO2 (90-95%) has been lost through impact erosion, sputtering processes associated with the solar wind and sequestration within the crust [3]. This has been correlated w...
