Periodic boundary
 

Dear All,

i struck up with problem regarding periodic boundary,

i had 6 tubes parallely arranged and these are attached to 6 burners. In the burner combustion was considered and hot gases coming from burner enter into the tubes. from bottom air was blowed to get the hot air at top. we want to check the skin temperature of the tubes. so considering one burner combustion and pipe, is it translate to others using periodic boundary, without solving remaing burners combustion. pl suggest the way to solve this.

Thanks and Regards Rao
