Turbine Blade Tip Leakage Flow Control: Thick/Thin Blade Effects

An experiment was conducted in a linear cascade of Pak-B blades for an exit Mach number of 0.3 to simulate the flow in the tip-gap region of a low pressure turbine blade row. The experiment focused on the independent effects of thickness-to-gap and gapto-chord ratios on the tip-gap flow behavior. Two extreme gap-to-chord ratios of 5% and 8% were chosen, for which four thickness-to-gap ratios we...

Effect of a ring type barrier and rotational speed on leakage flow of gas turbine brush seal

This paper investigates the effect of inserting a ring type barrier on leakage flow of brush seals with different bristles clearances (the distance between bristle pack tip and rotor surface). The ring is placed on both upstream and downstream sides of the bristles. An axisymmetric CFD model is employed to calculate radial pressure distribution along backing plate, axial pressure variation on r...

Turbine Blade Tip Cooling and Heat Transfer

ii ACKNOWLEDGEMENTS Behind every success, there is inspiration or support of at least one person. In my case, it was a group of people including my mentor, my family, and my friends. First of all, I would like to thank Dr. Srinath Ekkad for his guidance, wisdom, and financial support. I do not think many advisors would go to the lab to help his student running an experiment. Whenever I had any ...

Numerical Analysis in the Flow Field of a Labyrinth Seal

This paper pRisents nwneric:a.l analysis of the incompressible turbulent flow field in a single cavity of the stepped multi-cavity seal. The dimensionless bulk pressure drop for the cavity with and without groove has been investigated for four different Reynolds numbers and three different shaft ro~ating speeds. SIMPLER algoritlun is applied to solve the NavierStokes equation and lowReynolds nu...

An Investigation into Turbine Blade Tip Leakage Flows at High Speeds

The effect of the blade tip geometry of a high pressure gas turbine is studied experimentally and computationally for high speed leakage flows. For this purpose two simplified models are constructed, one models a flat tip of the blade and the second models a cavity tip of the blade. Experimental results are obtained from a transonic wind tunnel to show the static pressure distribution along the...
