Reasonable reynolds number
Webb29 mars 2006 · Finite-difference solutions of the equations of motion for steady incompressible flow around a circular cylinder have been obtained for a range of Reynolds numbers from R = 5 to R = 100. The object is to extend the Reynolds number range for reliable data on the steady flow, particularly with regard to the growth of the wake. Webb26 aug. 2007 · The coolant generally runs a Reynolds Number greater than 2350 (transition to turbulence). The equivalent heat-transfer coefficient on the coolant side is anywhere from say 2000 to 20,000 W/m2.K, depending on the coolant flowrate & tube turbulence mechanism eg. dimples, turbulator etc.
