  1. I'm trying to use cfx to obtain flow field of liquid which is confined in a cylindrical domain, the domain is covered by "wall", no other boundary ... I used rotating reference frame and non rotating reference frame method to solve it and made comparison about the velocity field. ...
  2. CFX-Pre enables you to specify a domain that is rotating about an axis. When you specify a Rotating Frame of Reference, you must also specify the angular velocity, ω ... Rotating Wall This option applies to both stationary and rotating domains and allows the wall to rotate with a specied angular velocity. ...
  3. 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. ...
  4. 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. ...
  5. 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... ...
  6. This case requires a rotating domain placed around the rotor while the stationary wall and baffles remain in a stationary domain. ... relative velocity formulation • Uses the absolute velocity as the dependent variable • Can be used by enabling “Alternate Rotation Model” in CFX-Pre setup... ...
  7. For rotating domains, the axis will default to the domain axis of rotation. ... (See Mesh Deformation in the CFX-Pre User's Guide for information about activating mesh deformation for the domain.) If this is the case, the wall velocity (as set above) can be made relative to the boundary frame or to the mesh... ...
  8. . In rotating frames of reference. SST. see Isothermal in the CFX-Solver Modeling Guide.1.12) where is the flow velocity.3. 17). ... (1. 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... ...
  9. ...rotating frames of reference • Alternate rotation velocity advection model • Multiple frames of ... Some of the beta features available within ANSYS CFX software at release 13.0 include: Released ... for non-walls • Mesh adaption for porous domains • Domain-based solver control • Additional models... ...
  10. Экспортировал в ansys cfx11 запускал на счет, проходит ... Type = WALL Frame Type = Rotating Location = HUB.1 BOUNDARY CONDITIONS: WALL ... BUOYANCY MODEL: Option = Non Buoyant END DOMAIN MOTION: Alternate Rotation Model = true Angular Velocity... ...
