Laminar flamespeed :Rahim correlation

egidio.cassone · September 4, 2019, 02:45

Hello,
This correlation is quite interesting ( as that propoosed in https://doi.org/10.1177%2F1468087417720018) as it should provide more reliable values in a wider range of operating conditions.

The question is :how to activate it?

Thankyou,

Egidio

Go to Case setup -> Physical Models -> Combustion modeling -> Models (G-Equation) -> Laminar -> Laminar flamespeed. Here you can choose multiple options for flamespeeds. Rahim correlation should be available as one of the options.

Thank you for replying... Which version of studio is that? On the May release there is not that option and on the latest release notes there is no mention about this enhancement

This option might not have propagated to the last Studio release. But it has been available from v2.4.20 in the solver (release notes should have that). You will have to manually change the sl_model to 3 in combust.in.
