Search for industrial case in paper using PyFR

[luli]

Is there such an Industrial case (such as airfoil) in any paper that can show the comparison between PyFR and experimental results ?

[WillT]

There are some comparisons shown in this paper: Redirecting

But also in some other more recent papers there are some experiemental comparisons.

In this paper, PyFR use DNS p5 scheme , but I remember that pyfr use LES model ? How to switch model in PyFR ?

[p.vincent]

PyFR does not have an LES capability (there are no sub grid models implemented). You can run ILES though (under-resolved DNS).

So in boundary layer , PyFR use wall resolved instead of wall modeled method?

This question has been asked and answered a number of times before. See:

Turbulence model in PyFR

Dear All, I have read an article “Brian C. Vermeire, Freddie D. Witherden, Peter E. Vincent: On the utility of GPU accelerated high-order methods for unsteady flow simulations: A comparison with industry-standard tools. J. Comput. Physics 334: 497-521 (2017).”, and I am trying to simulate the circular cylinder and SD7003 aerofoil cases. Thank you for providing the mesh and setup files for the simulation cases in the article by the authors, and update the setup file of the SD7003 case for recent…

Are there Turbulence models in pyfr?

Hello! I would like to know about models for turbulence closure on PyFR. Which models are implemented on it? Is there any RANS model? Thank you so much.

WMLES in PyFR

Hi all, I would like to implement a basic Algebraic Wall Model in PyFR. The model consists of 2 simple equations for the turbulent boundary layer: one for the shear stress and another for the heat flux (in case of an isothermal BC). As a 1st attempt, we can restrict the Wall Model to probe the LES quantities within the first element off the wall. Another modification is that the we might need a slip condition that will let the velocity to be driven by the imposed shear stress. Regarding elemen…

Some questions about implicit LES

Hi, everyone I wonder can a DNS code directly be used to perform ILES without any revision. The difference between DNS and ILES is the requirement of mesh resolution from the view of implemention, right? Moreover, does the ILES have the procedure of filtering? What properties are needed for the numerical scheme to be suitable for ILES？ Best regards
