Bulk flow controller / spatial average plugin

[Marius]

Hello,

I´m using the code from the supplementary material of https://doi.org/10.1017/jfm.2019.520 for channel flow simulations.
Could you please provide a sample ini file, to see which parameters are necessary / available for the bulk_flow_controller and spatial_average plugins, to adjust a constant bulk velocity and get y-dependent statistics like u_rms ?

Regards,
Marius

Hi Marius,

I have a branch of PyFR that does recirculation with body forcing to maintain a constant bulk velocity :

https://github.com/tarikdzanic/PyFR-RC

The forcing is controlled by the following parameters in the .ini file:

[soln-plugin-inletforcing]

inletname = 'periodic_0_l'

area = 9.01441

mdotstar = 1

'Inletname' is the inlet (or outlet) boundary name in the mesh file (which has to be a periodic boundary condition),  'area' is the total inlet area, and mdotstar is the desired mass flow rate normalized by area. 

Best,

Tarik
