Temperature statistics in turbulent Rayleigh–Bénard convection with a Prandtl number of Pr = 12.3
AIP Advances, 2022 The transport of plumes in turbulent convective systems must be understood to study the mantle and various industrial applications. We measured the probability density function P(T) of the temperature at various radial and vertical positions in the bulk ...

Diffusion Processes in the A-Model of Vector Admixture: Turbulent Prandtl Number
EPJ Web of Conferences, 2018 Using analytical approach of the field theoretic renormalization-group technique in two-loop approximation we model a fully developed turbulent system with vector characteristics driven by stochastic Navier-Stokes equation. The behaviour of the turbulent

Archives of Mechanics, 2022 The fully developed turbulent Boussinesq convection is known to form large-scale rolls, often termed the ‘large-scale circulation’ (LSC). It is an interesting question how such a large-scale flow is created, in particular in systems when the energy input

Numerical Heat Transfer Study of Liquid Metal in Triangular Rod Bundle Based on k-ε-kθ-εθ Model
Yuanzineng kexue jishu, 2022 Compared with the constant turbulent Prandtl number (Prt) model, a four-equation model considers the difference between the velocity and temperature boundary layer of liquid metals by introducing the turbulence time-scale, which is expected to improve ...

Theoretical and Applied Mechanics Letters, 2021 We propose a theoretical model for spatial variations of the temperature variance σ2(z,r) (z is the distance from the sample bottom and r the radial coordinate) in turbulent Rayleigh-Bénard convection (RBC).
