ESTIMATION OF THE CRITICAL RAYLEIGH NUMBER AS A FUNCTION OF THE INITIAL TURBULENCE OF THE BOUNDARY LAYER AT A VERTICAL HEATED PLATE

Based on stochastic equations and equivalence of measures, formulas of critical Rayleigh numbers depending on the initial turbulence of the boundary layer on a vertical heated plate are derived analytically. The results of calculations using new formulas show agreement with experimental data for the first and second Rayleigh numbers.
