Computing reynolds number
WebWhat is the best characteristic length to calculate Reynolds number downstream of the block at the red point (as is shown in the schematic) View. WebLet's imagine we calculate a Reynolds Number of 4x10^4 (yes, I'm rigging for simplicity). We see that this is in the Reynolds Number range for turbulent flow, so we proceed with the Moody Chart. Next, let's say we calculate a unitless relative roughness of 0.003. From here, we sketch a line following the curve contours, going left, as seen in ...

WebMay 26, 2024 · We need to define effective viscosity of the fluid for a given a set of fluid flow conditions to determine Reynolds numbers of a non-Newtonian fluid. Please refer to the paper below for more information. … WebThis can be transformed into an expression involving the Reynolds number by making the correspondences: T=Mdt and TU=L. That is, the characteristic time for a flow is the time for fluid at velocity U to move a distance L, and the number of time steps resolving time T is M. With these relations the stability condition is then, M = 4N 2 /R.
