Wang, J. Y.-H. Chang.   DESIGN OF TESLA TURBINE Abstract: The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional Tesla turbine is also known as the boundary layer turbine, cohesion-type turbine, and Prandtl layer turbine.

National Aeronautics and Space Administration.;]. A commercial CFD code is used to compute the flow field within the first stage impeller of a two stage axial flow pump.

The code solves the 3-D Reynolds Averaged Navier Stokes equations in a. A commercial CFD code (FLOTRAN) is used to solve the 3-D Reynolds Averaged Navier Stokes equations in a rotating cylindrical coordinate system.

The standard k−ε turbulence model is used. The meshes for this study nodes nodes for the axial flow impeller, nodes for the mixed flow by: The viscous effects and the influence of cooling air mixing are considered by the use of selected loss correlations for profile, tip leakage, secondary flow and mixing losses in the S 2m-plane in terms of entropy.

The method is applied to the four-stage high-temperature gas turbine Siemens KWU VCited by: 5. The New High Resolution Method of Godunov's Type for 3D Viscous Flow Calculations. The computation of the 3D viscous flow through a turbine stage has been carried. This paper describes the introduction of three-dimension (3-D) blade designs into a 5-stage axial compressor with multi-stage computational fluid dynamic (CFD) methods.

Prior to a redesign, a validation study is conducted for the overall performance and flow details based on full-scale test data, proving that the multi-stage CFD applied is a relatively reliable tool for the analysis of the Cited by: 4.

Regarding the intake section, the flow remains three dimensional and a 3-D flow simulation tool should be used in order to convey the flow information down to the compressor.

Despite the fact flow non-uniformities are to a certain extent attenuated until they reach the compressor section, applying a 0-D or an 1-D flow simulation method will Author: Ioannis Templalexis. An axial-flow compressor stage is designed to give free-vortex tangential velocity distributions for all radii before and after the rotor blade row.

The tip diameter is constant and m; the hub diameter is m and constant for the stage. At the rotor tip, the flow angles are as follows: absolute inlet angle, α 1 =30°.
