Abstract:
This paper gives a detailed explanation about the effect of particle injection on blade length and profile loss coefficient with variation of inlet velocity. Two Dimensional geometry of rectilinear cascade with six blades is created in Gambit® 2.4.6 software and flow behaviour is analyzed using fluent 6.3.26. Air at inlet velocity 50m/s, 100m/s and 150m/s with injection of ash, steel and water particles of 50µm, 100µm, 200µm and 300µm is passed through the cascade. The profile loss is decreased by increasing the velocity for a blade span. In case of ash particles of 50µm, profile loss is 17.92% by increasing velocity from 50m/s to 150m/s, 17.89% in case of steel particles,17.15% in case of water particles. We analyze that the effected length on the suction and pressure side of the blade will increases by increasing the velocity and diameter of injected particles.
