Hi all,
I am working on heat transfer rate in 3d heat exchanger in fluent. I have calculated both hi and hd heat transfer coefficicent manually. But I couldn't put both coefficient in boundary conditions of walls in DesignModeller , external flow around cylinders is defined fuid and have been created name selection '' wall_thickness_1 and I have defined fluid in pipe and it have been created named selection wall_thickness_11 Moreover shell conduction are defined is for conduction heat transfer rate in wall_thickness_11 How can I give both heat transfer coeff.? for wall_thickness_1 (that is external section) can I give hd coeff ? and the other one is , for wall_thickness_11 can I give hi coeff? Kind Regards, |
