Reynolds Number and Viscosity in the Solar Wind

The Astrophysical Journal
The Reynolds number is a key dimensionless parameter used to distinguish turbulent flow from laminar flow. We present generalized expressions for both the Reynolds number and viscosity, incorporating the spectral indices of the inertial range, applicable

Experimental Study on Reynolds Number Evolution of Gas-Filled Coal

Geofluids, 2019
The flow state of gas in coals is very complicated. We should pay attention to whether the permeability calculated by Darcy’s law is in accordance with the actual situation.

Prandtl number effect on near wall temperature profile in high-Reynolds number channel flows

Nihon Kikai Gakkai ronbunshu, 2014
Prandtl number (Pr) effects on characteristics of the thermal boundary layer were investigated by means of Direct Numerical Simulations (DNS) in high-Reynolds number turbulent channel flows. The molecular Pr conditions were changed from 0.71 to 25.0, and
