DETERMINATION OF CRITICAL REYNOLDS NUMBERS FOR NONISOTHERMAL FLOWS BY USING THE STOCHASTIC THEORIES OF TURBULENCE AND EQUIVALENT MEASURES

The theory of equivalent measures and systems of stochastic equations for nonisothermal continuous medium flow is applied. The analytical expressions of critical Reynolds numbers depending on the Eckert number and initial turbulence for nonisothermal and compressible Newtonian medium flows for a smooth flat plate and a round tube are discussed. A comparison of the calculated values of the critical Reynolds numbers and experimental data is presented.
