Dear Sir,
You had once mentioned that TECPLOT could be used to get the attached picture? 1.could you explain me how to do it in TECPLOT (as I am not getting both contours and velocity vector in one picture.) I have simulated the results for different ang. vel. & geometries but only for 10,30 and 45 deg meshs. 1.But for nicer interpretation I want to know the particle pathline for the complete 360 degs or any other way so that I can analyze that its WVF or TVF and stuff like that......... is there anyway, that I can do it ? |

Yes Sir the mesh file were useful to me, as it provided me an idea of how many nodes to create in the different sections.
I din't simulate the flow in our mesh file as I wasn't able to convert the top and bottom faces into periodic boundaries in FLUENT solver 6.3.26 . THank you !! Referring to my last post's image, is it possible to get the black colored vectors in the vel. contours in tecplot ? ANd how can I deduce that at a particular flow rate the flow is WVF or TVF ? |

Yes black vectors and velocity contours can be displayed simultaneously in Techplot. What is WVF or TVF? Last edited by Far; November 3, 2012 at 11:26. |

TVF- Taylor Vortex FLow WVF comes after TVF at higher reynolds number. Please let me know the procedure for plotting it in TECPLOT too !! |

I have specially installed fluent 6.3.26 to illustrate how to make the translational periodicity in Fluent (or rotational periodicity as you prefer). Keep in mind ICEM does not allow me to add both.

Sorry for delay, I was out for a couple of days;
I think this can be evaluated by look at the pathlines; look at the attached picture I found on google to identify different flows. Daniele |

You can use also tecplot, with the "slice" feature; on the slice window option choose to plot vectors. However this is simpler with fluent itself or cfd-post. Daniele |

if you want to know your flow near the surface wall of your domain then you can use " k-episilon" and if you want to know far away from the surface wall then use "k-omega

I have a question, sorry if it is stupid.
How did you increase the number of divisions in the radial direction for the mesh? I have a school project now where we are trying to model this flow, but we are having extreme problems creating a regular mesh which has enough divisions in the radial direction (from the inner wall to the outer wall). Any help you could provide would be very appreciated. Again, sorry if this is a stupid question. |
