SIMTEC used CFD to study the air flow inside an Air-Curtain. Air–Curtains are usually placed over doors and openings in commercial stores, shops and other public spaces. They create an air jet of sufficient kinetic energy, that will not allow the flow through the opening, hence thermally separating the two areas.
The simulation revealed the creation of recirculation zones and high friction values (energy losses), that reduce the performance of the Air-Curtain. Furthermore, high levels of turbulence were calculated, contributing to the noise during operation. Useful conclusions were derived, concerning the need for changes in the design.
