* This is a simulation case for a viscoelastic fluid described by the Exponential form of
|
|
the Phan-Thien-Tanner constitutive model (PTT-Exponential).
|
|
The simulation is about the flow past by a cylinder.
|
|
|
|
*** This is only an illustrative case for the PTT-Exponential constitutive model. Therefore,
|
|
there are not more details published until now for this model using this geometry
|
|
and viscoelasticFluidFoam solver. Some adjustments can improve the results, once the mesh
|
|
used was coarse to make the simulation more fast.
|
|
|
|
*** The parameters for constitutive model was obtained from:
