摘要：

This paper describes a new device for aerodynamic sealing of openings for the passage of strip-like material in chambers, e.g. in industrial furnaces, dryers, and for clean rooms. A numerical prediction procedure for the flow generated by the sealing device is presented. The influence of the relevant flow parameters upon the sealing efficiency is systematically analysed. Theoretical predictions are validated through concentration measurements in a physical model of a strip flotation furnace. The advantages of the new device-contactless sealing and minimized leakage of the atmosphere from inside the chamber to be sealed-are discussed in detail.
