  1. Firstly, I used rotating reference frame by assigning the control speed value omega to the "angular velocity" in the domain motion tab and zero velocity for wall velocity with no slip condition, so I can get relative velocity values from post-cfx. ...
  2. Visualizing the velocity on a boundary in CFX-Pre. Using the CFX Expression Language (CEL) to describe temperature dependent uid properties in CFX-Pre. ... This wall will be rotating, and therefore stationary relative to the rotating domain. ...
  3. ...and rotating frames of reference • Alternate rotation velocity advection model • Multiple frames of ... Burning velocity model (BVM) - Extended coherent flame model (ECFM), including wall quenching ... domains • Highly efficient parallel execution • Scalable memory usage Beta Features ANSYS® CFX... ...
  4. Once you have create the domain interface, you will see that CFX-Pre has automatically created some boundary conditions for the fluid and the solid side. You can then edit the fluid side boundary condition and set a wall velocity, or a counter rotating wall, or leave the walls as... ...
  5. For details on finite slip wall, see Finite Slip Wall in the CFX-Solver Modeling Guide. ... This option could be used to duplicate the counter rotating wall option in rotating frames by explicitly setting the angular velocity equal to minus one times the domain angular velocity. ...
  6. What is the difference between using a Rotating Domain and a Stationary Domain with rotating walls in CFX? ... If the flow is mainly rotating at a magnitude similar to the rotating wall velocity then the Rotating Domain is preferred. ...
  7. There are three different options for the wall velocity: Page 56 ANSYS CFX-Solver Theory Guide. ... This option could be used to duplicate the counter rotating wall option in rotating frames by explicitly setting the angular velocity equal to minus one times the domain angular velocity. ...
  8. В toolbox найдите иконку CFX и левой кнопкой мыши перетащите ее на свободное место в области ... Щелкните 2 раза по пиктограмме Default Domain в колонке слева. ... В панели слева перейдите во вкладку Boundary Details и поставьте галочку напротив Wall Velocity. ...
  9. Sample files referenced by this tutorial include: • InjectMixer.pre • InjectMixer_velocity_profile.csv • InjectMixerMesh.gtmANSYS CFX Tutorials Page 77ANSYS CFX Release 11.0. ... A wall for the hub and shaft in the rotating domain. ...
  10. Экспортировал в ansys cfx11 запускал на счет, проходит какое-то время ... DOMAIN MOTION: Alternate Rotation Model = true Angular Velocity ... им условие wall то они будут по умолчанию rotating и это не поменять . ...
