Pulsatile velocity inlet for pipe flow

OWAISM · November 4, 2016, 07:00

Kindly suggest how to give a pulsatile velocity inlet in a straight pipe flow.

Have a look at the swak4Foam package, which includes groovyBC and allows for time dependent boundary conditions to be used.

I want to use pisoFoam algorithm, how can I do that in it?
I m a kind of beginner, need some more details.

Hi Mohammad

It will gladly work with pisoFoam. You can install swak4Foam (after you have a valid openFoam installation) by following the following instructions of its OpenWiki page https://openfoamwiki.net/index.php/I...am/Downloading

For the usage of the groovyBC boundary conditions have a look at the examples also available. https://openfoamwiki.net/index.php/C...Usage_Examples

Otherwise search for groovyBC on this forum as well for lots of examples. http://www.cfd-online.com/Forums/ope...end-inlet.html

Cheers,
Brian
