It is a significant challenge to the designer to protect the turbine material from this severe situation.  A single stage gas turbine engine was modeled and simulated using commercial CFD solver ANSYS CFX  R.11. The modeled turbine stage has 30 vanes and 60 blades with a pressure ratio of 3.2 and a rotational speed of 9500 rpm. The predicted isentropic Mach number  and adiabatic wall temperature on the casing showed good agreement with available experimental data under the close operating condition. The effects of tip clearance heights and rotor  speeds have also been analyzed and compared one with  respect to others. Same typical patterns of leakage flow structures and heat transfer rate distribution can  be obtained in both steady and unsteady simulations. However, steady simulation underpredicted the  highest heat transfer rate. Because it couldn't capture the critical local high heat transfer phenomena caused  by the unsteady stator-rotor interactions.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844385632\"\u003e\u003ch3\u003eTip Leakage Flow Characteristics and Heat Transfer on Turbine Blade Tip and Casing - Unsteady Stator-Rotor Interaction\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844385632","offer_id":39471205056605,"sku":"9783844385632","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/366103d0-fce9-4a30-a2d9-f55fd04eae7c.jpg?v=1769148083","url":"https:\/\/shop.autorenwelt.de\/products\/gas-turbine-tip-leakage-flow-and-heat-transfer-von-md-hamidur-rahman","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
