It acts as an extra wall providing the extra heat transfer by its both sides. In this case the advanced fin configuration is examined. It provides the same surface area as single thermal bridge in impeller- like manner of surface interruption and shifting it around axes. The user can choose the bridge type, the flow regime, Reynolds number and type of the solution procedure in interactive mode. The PLANT is used to calculate the angle between the velocity vector and Z-axis to asses the validity of the parabolic option.
