МОДЕЛИРОВАНИЕ АЭРОДИНАМИЧЕСКОГО ШУМА ВОЗДУШНОЙ ПОДУШКИ

Air streams in the nature, in technical devices, in industrial systems of transportation on an air pillow generate aerodynamic noise which is the negative factor from a position of ecology. The aerodynamic noise generated by an air stream, arises due to turbulence of this stream. Modeling of aerodynamic noise can be carried out a method of transformation of the equations of movement, indissolubility and entropy for air streams. Results of construction of model of potential of speed of small indignations of a turbulent stream in an air pillow are submitted. The ratio connecting hydrodynamic characteristics of a turbulent stream with its acoustic characteristics in an air pillow is shown. The formula for engineering calculations of a level of the aerodynamic noise formed by an air pillow, formed is received by a single slot-hole aperture.
