A pilot study of aero- and thermodynamic processes in the apertures equipped with heated air curtains
Annotation
The problem of comparing and selecting heated air curtains (HAC) always springs up while designing life support systems for the rooms with open apertures. Growing requirements to this kind of equipment compel the designers to not only develop modern methods of calculating aero- and thermodynamic processes for HAC-equipped apertures but also carry out detailed experimental studies of the air flow in such aperture for different purposes, including the testing of new mathematical models for adequacy. This work presents the results of experimental research on aero- and thermodynamic processes in the apertures with horizontal HAC having low (3 kW, discharge 400 m3/h) and medium (6 kW, discharge 1000 m3/h) heating capacity. The experimental test bench is described in detail, and the error for the conducted research has been identified. The studied HAC may be installed in any apertures under variable aero- and thermodynamic conditions of the environments.
