I am trying to study heat transfer between flue gases and air in a cross flow heat exchanger. I have a recuperator in which air is flowing and external shell in which flue gases are flowing. I have imported the geometry from solidworks and now I want to fill air within the recuperator and flue gas in the shell but I am unable to do so. Anyone with any idea how can I do that and proceed further with my problem will be of great help.
if you need any further details regarding it, kindly let me know.
thanks!
