i am trying the problem jet impingment on cirular cylinder with constant heat flux condition maintaned on cirualr cylinder , but the temperature countour on cylinder surafce is wrong. The temperture valve at stagnation piont is high to as campare the end portion cylinder. it see the temperature results is coming revesre trends. Is it the problem of bounadry of constant heat flux.
I have checked the constant tempearture bounaday condition at cylinder surface, the heat flux simulation results are corrrect on cylinder surface.

Hello,

Did you use the correct symbol (+ or -) for the heat flux boundary condition?

I got correct results. I have changed sign the heat flux postive to negtive.
thank

But what is the problem of (+or-) sign. can you provide me some doucement for learing.
thank

You can find this information in theory guide of Code_Saturne.
