Compressible helical turbulence: Fastened-structure geometry and statistics

Reduction of flow compressibility with the corresponding ideally invariant helicities, universally for various fluid models neutral and ionized gases, can be argued statistically associated geometrical scenario in Taylor–Proudman theorem its analogs. A “chiral base flow/field,” rooted generic intrinsic local structure, as well an “equivalence principle,” is explained used to bridge single-structure mechanics helical statistics. The electric field fluctuations may similarly depressed by (self-)helicities two-fluid plasma model, geometry lying relation between density fields a Maxwell equation.
