MICROSCALES OF TURBULENCE AND HEAT TRANSFER CORRELATIONS [PDF]
Annual Review of Heat Transfer, 1986 Abstract The small-scale structure of forced, turbulent flows developed after Taylor and Kolmogorov is extended to that of buoyancy-driven flows. A thermal microscale η θ ∽ 1+Pr Pr 1 4 Vɑ 2 P B 1 4 is proposed. Here Pr = v a denotes the Prandtl number and ℘B the production of buoyant, turbulent energy. Three

Comparison of numerical results of turbulence models for the problem of heat transfer in turbulent molasses [PDF]
E3S Web of ConferencesThe study introduces Malikov's two-fluid methodology along with the RSM turbulence model for simulating turbulent heat transfer phenomena. It elucidates that temperature fluctuations within turbulent flows arise from temperature differentials between the

Self-sustained biphasic catalytic particle turbulence
Nature Communications, 2019 Turbulent systems are particularly suitable for heat transport. Here the authors add active particles to a turbulent system, and the coupling of turbulent convection and the collective dynamics of active particles leads to a 500% enhancement in heat ...

Numerical Study on Laminar-Turbulent Transition Flow in Rectangular Channels of a Nuclear Reactor
Frontiers in Energy Research, 2020 Laminar-turbulent transition flow can be observed in thermal engineering applications, but the flow resistance and heat transfer characteristics are not fully understood.
