HOW TO APPLY CONSTANT HEAT FLUX OVER WALL OF TUBE

K.VENKATACHALAPATHI

sir, i'm doing my master's degree project in cfd,my project is dealing with internal tappered finned tube,i use to model by gambit and analyse by fluent. my boundary condition is constant heat flux over the entire wall surface,inlet temperature and inlet velocity,laminar flow. for applying heat flux over the wall i have little bit confusion, Because while i modeling i modelled only fluid flow area,suppose if i apply heat flux value means it takes value same as outer region as well as internal finned area. plz kindly send help tutorial for internal tappered finned tube as well as your kind suggesion..
