One minus 19.7 divided by this number is proportional to the Strouhal number, which governs the formation of von Karman streets.
One minus 19.7 divided by this number is proportional to the Strouhal number, which governs the formation of von Karman streets. For a packed bed, its denominator contains one minus the voidage. One version of this value is the ratio of magnetic advection to magnetic diffusion. It appears on the x-axis of a Moody diagram plotted against the Darcy friction factor. This value can be expressed as the ratio of (*) inertial forces to viscous forces, and is equal to the velocity times length scale divided by kinematic viscosity. At high values of it, eddies and vortices appear in the flow. For 10 points, name this dimensionless parameter which determines whether flow is laminar or turbulent.
