Your order will be reviewed by our experts in the shortest possible time, and if we need more information about the proposed project, we will be in touch with you. The mathematical model is presented for prediction of frost layer parameters. At the change in reference frame between the rotor and stator, two different interface models are considered. Th e ge om et ry to be mo de ll ed co ns is ts of a si ng le st at or bl ad e pa ss ag e and two rotor blade passa ges, as shown in Figure 12. The existing Frozen Rotor simulation will then be modified to define the transient Rotor-Stator simulation. Introduction mixing plane One of the most common practical engineering applications of fluid mechanics is the design of turbomachines. Usually users have difficulty in knowing what software to use for what engineering challenge they face.
Finally, lanuch the job, rember to specify the file presenting the resutls of Frozen Rotor simulation as the initial flow field. Turbomachines are the hearts of industries. The transient Rotor-Stator simulation will be performed using the steady-state Frozen Rotor asan initial guess. Periodic boundaries are used to allow only a small section of the full geometry to be modeled. The frozen rotor solution is used as an initial guess for the transient rotor-stator simulation.
The results will be viewed using the Turbo-Post feature. After completing the required information to examine the proposed project, and confirming your request, the time, conditions and costs will be sent to you during the contract. Steady state solution is shown and transient and transient blade row especially time transformation are used. The software provides researchers with flow visualization tools in the virtual environment. Then, set the boundary conditions and specify solver settings. First a solution is obtained using a frozen-rotor model.
In this example, the rotor rotates about the Z-axis at 523. The Russian tutorial: Ansys Turbomachinery tutorials : Ansys TurboSystem:. Generating the flow path of a turomachine can be automatic or a manual process. These problems give results but when the user uses them without knowing the numerical models used it would be difficult for him to know that the obtained results are correct or not and how accurate they are. This paper is focused on frost deposition phenomena on elliptical cylinder. . It is also provided with a visualization package that is very powerful with its provided built in functions.
Had you seen ansys tutorial on centrifugal compressor in ansys help? You should also use standard K-epsilon model for the turbulence modeling and wall function model. To model the interaction between the rotor and stator define a mixing plane. In a single-stage axial flow turbomachinery, these configuration is typical. This process will take place as soon as possible. In this tutorial, both methods are shown.
To train modeling of mixing plane in this section, an axial fan with the rotor and stator is simulated in one step. The automatic is shown by Ansys BladeGen and Ansys Vista. If you have any question, you can contact to our online support section the fixed blue tab below the page. Circumferential averages of total pressure should be displaced on a surface. Then, you should modify the materials. T he rotor rotates about the z-axis while the stator is stationary. Once your flow simulation is sonic, supersonic, ultra-sonic then you need to use a different type of solver for the purpose of capturing shock waves.
The full geometry contains 60 stator blades and 113 rotor blades. Use Pressure Based solver for performing the calculations. Check out the links after the description. To help you visualise how the modelled geometry fits into the full geometry, Figu re 12. Periodic boundaries are used to allow only a small section of the full geometry to be modelled.
This model is based on heat transfer coefficient distribution on the surface of such elliptical cylinder. In order to view of the interaction of rotor and stator simultaneously, you should consider them in a single computation. The Inflow and Outflow labels show the location of the modelled secti on in Figu re 12. The manual method is shown for an axial compressor. . . .
