BladeModeler 11.0Practical 9:,Axial Turbine Rotor,Concepts,In this tutorial we will:Input the initial blade settingsIn meridional view, modify the hub and shroud curves and location of inletDefine a leading and trailing edge typeExport the model to TurboGrid,Initial Design Parameters,CFX-BladeGen allows the user to create a blade system from scratch, using one of six standard initial configuration types. For this example, a Normal axial is used.Select the File | New | CFX-BladeGen Model menu command or toolbar button which will display the Initial Meridional Configuration DialogSelect the Normal Axial tabEnter the parameters for the initial blade layout (shown on the following slide).Be sure to select : Prs/Sct mode in the bottom right cornerPress Enter or select the OK button to continue,Normal Axial Turbine,Design parameters to be entered for the Normal Axial Template:,,,Blade Angles and Thickness,Select blade angles and blade thickness as shownNumber of blades = 43,Optimizing Meridional View,Optimizing the meridional viewVery important operation in the meridional view is to define the shape of the hub and shroud curve, starting from inlet to the outletThe endpoints for these curves were specified when Initial Design Parameters were entered.,Optimizing Meridional View,There is an obvious need to adjust an inlet region and shroud curve Desired :,Adjustment of Inlet Section,Maximize the meridional view window (Top-Left View Window)Double click the shroud inlet point (top left) and enter: - 45 and 80 for the horizontal and vertical values. Click OKDouble click the hub inlet point (bottom left corner) and enter: -45 and 60 for the horizontal and vertical values. Click OK.Leave outlet points at the hub and shroud as they are.,,Blade Shroud Curve,Adjust Blade Shroud CurveLeft-click the blade’s shroud curveRight-click the mouse and select: Convert Points > Spline Curve Points…In the Point Count Dialog, enter 5 points and select OK.Drag points individually to obtain the desired shape of shroud curve (see next slide),Meridional View,After adjusting, the meridional view appears as shown:,LE and TE Type Definition,Prescribe the Leading/Trailing Edge EllipseSelect Blade | Properties menu commands, or:Click the toolbar button located on the left hand side of the CFX-BladeGen window to set the blade properties. Set the LE/TE Ellipse tab, adjust the values as shown on the next slideAll other values can remain unchanged.,LE / TE Type,Model Properties Dialog,Set the model properties:Model > Properties,Ensure Model Units are Set,,Save Geometry,Save the geometryClick the Save as iconName the file AxialTurbineRotor.bgd,Export Geometry,Export the geometry to TurboGridClick the TurboGrid Input Files iconAccept the default filenames,
