Аннотация
An analysis of the basic properties of the scalar frequency-wave spectrum of turbulent pressures, representing the total energy of the wave components of the turbulent pressure field with a given wave vector modulus, has been carried out. Consideration of the scalar spectrum, which has independent applied significance, allows us to visualize the energy distribution of turbulent pressures in a wide range of frequencies and wave numbers. Based on well-known vector wave field models, relations are proposed for estimating the reduced scalar spectrum. The degree and nature of the parametric influence of the Mach and Reynolds numbers are determined.
