A multi-block, three-dimensional Navier-Stokes code has been used to compute heat transfer coefficient on the blade, hub and shroud for a rotating high-pressure turbine blade with film-cooling holes in eight rows.

Film cooling effectiveness is also computed on the adiabatic blade. Wilcox’s k-ω model is used for modeling the by: 4. Book. Gas Turbine Heat Transfer and Cooling Technology Authors: J.C.

Han, S. Dutta and S.V. Ekkad. Publishers: Taylor & Francis, New York, A comprehensive compilation of the available cooling techniques used in the Gas Turbine industry has been encapsulated in.

The blade tip region, particularly near the trailing edge, is often very difficult to cool adequately with blade internal coolant flow, and film cooling injection directly onto the blade tip region can be used in an attempt to reduce the heat transfer rates directly from the hot clearance flow to Cited by: A three-dimensional Navier–Stokes code has been used to compare the heat transfer coefficient on a film-cooled, rotating turbine blade.

The blade chosen is the ACE rotor with five rows containing 93 film cooling holes covering the entire span. This is the only filmcooled rotating blade over which experimental data is available for comparison.

The above survey indicates that the interaction between the film coolant flow and the mainstream over an actual blade surface is not well understood even though it is known to have a large influence on the heat transfer characteristics of film-cooled blades (Garg and Gaugler, b).

We need to model this interaction in order to incorporate Cited by: used to study the within-hole and near-hole physics in relation to heat transfer on a film-cooled blade.

The flow domain consists of the coolant flow through the plenum and hole-pipes for the three staggered rows of shower-head holes on the VKI rotor, and the main flow over the blade.

A multi-block grid is generated that is nearly orthogonal to. @article{osti_, title = {Impact of rotor-stator interaction on turbine blade film cooling}, author = {Abhari, R.S.}, abstractNote = {The goal of this study is to quantify the impact of rotor-stator interaction on surface heat transfer of film cooled turbine blades.

In Section 1, a steady-state injection model of the film cooling is incorporated into a two-dimensional, thin shear layer. blade and the rotor passageway, higher heat transfer occurs over the blade tip due to the tip leakage flow, while there is a noticeably lower value of heat transfer in the rotor passageway.

The thermal analysis is based on a simplified conjugate heat transfer analysis of flow in a cooling passage of a turbine blade as shown in Figure 7 and assumes that the airofoil; (a) metal temperature is the average surface temperature at the airofoil midspan, (b) is exposed to the maximum hot gas temperature profile at the blade inlet, and (c Cited by: 1.

The influence of the unsteady wakes and shock waves on the heat transfer to a film cooled rotor blade was studied for five film cooling configurations using a rotating bar apparatus in front of a 2-D cascade. Heat transfer measurements were made using thin film gauges placed at the mid-span of the test blade.
