From the author: Numerical calculations of the air flow and heat transport processes in film blowing have been made, considering the turbulence of the air flow. The parameters air mass flow, air temperature, air velocity, and angle-of-attack have been varied. The results have shown that the air mass flow has the strongest influence on cooling in the processing window examined. So the mass flow is a very efficient actuator of a film thickness control system. Moreover, the angle-of-attack together with the bubble shape is responsible for the occurrence of vortices. Such vortices can be the reason for unstable behavior in the bubble forming zone and hence for increased thickness tolerances of the film.
