WebFeb 3, 2024 · The probability density functions (PDFs) of both dissipation rates are found to deviate significantly from a log-normal distribution. The PDF tails can be well described by a stretched exponential function, and become broader for higher Rayleigh number and lower Prandtl number, indicating an increasing degree of small-scale intermittency with … WebFeb 28, 2024 · The Lagrangian LComplex is real for a conservative system and complex for a dissipative system. Using the Lagrange-Euler equation for variation of q ∗, that is, Λq ∗ LComplex = 0, gives Equation m which leads to the required equation of motion n. The canonical conjugate momenta are given by. p = ∂LComplex ∂˙q ˜p = ∂LComplex ∂˙q ∗.

WebOct 15, 2024 · The multi-phase Rayleigh–Bènard convection has been weakly investigated, even though it plays a leading role in the theoretical and applied physics of the heat transfer enhancement. For the case of moderate turbulent convection, a rather unexpected result is an unusual kind of wind reversal, in the sense that the fluid is found to be strongly … WebApr 12, 2024 · It was initially proven that if the conditional dissipation rate is modeled to be a constant, then a normal probability density function (pdf) preserves its shape and is always a normal pdf. 4 4.
