WebWhat is the critical Reynolds number for flow over cylinder? The flow past a circular cylinder at critical Reynolds numbers of Re = 2.5 × 105, 3.8 × 105, 5.3 × 105 and 6.5 × 105 is … WebReynolds number in that problem as well. It is defined as . Re. p. dV. ρ µ = We found that the drag coefficient, which is a dimensionless drag, depends on this Reynolds number. The flow past a sphere is more involved than that in a tube. At high Reynolds number, a boundary layer, in which viscous effects are important, forms on the sphere ...
