Mechanical scenario for the reaction: neutron --> proton + electron +   antineutrino
  Small perturbations of averaged ideal turbulence reproduce the electromagnetic field. The luminiferous medium has the relatively low pressure and high energy. A vapor bubble in the fluid models the neutron. The bubble stabilized via creating in the fluid a field of the positive perturbation of the turbulence energy serves as a model of the proton. An isle of the fluid that produces the respective field of the negative perturbation of the turbulence energy models the electron. The antineutrino corresponds to a local positive disturbance of the turbulence energy needed in order to compensate the difference in perturbations of the energy produced by the electron and proton.
