EdR and corus, thank you for your input.
Of course I don't expect the same solution between plain stress and plain strain. With regard to model asymmetries, the generalized plane strain model is exactly the same as the plane stress model, except in the batch file I change plane strain to plain...
Geometry: concentric thick wall tubes, with differential thermal expansion. Software: ANSYS 10.0.
If I use plane stress elements, the solution for a 1/4 cross-section model with symmetry BC coincides with that for a full model which recovers exactly the analytical solution.
If I use 1/4th model...
I'd like to measure TBL pressure fluctuations on the surface of a small tube (~.370" DIA), in water (I know it's different from aerodynamics measurements - air- but nevertheless...). I found a sensor that fits, but what's next? I have some specific questions, but any other comment on related...
Only the lift is perpenndicular to uniform mean flow (taken as the opposite from that of wing/airfoil, and away from it), while drag is in the same direction as the mean uniform flow. You end up with two perpendicular forces.
Lift can be related to the ciculation around an airfoil (and...
I'd like to measure TBL pressure fluctuations on the surface of a small tube (~.370" DIA), in water. I found a sensor that fits, but what's next? I have some specific questions, but any other comment on related work/expereince is welcomed:
1. should the sensor be flush, or at the bottom of a...
