http://secretmans.fr/?p=2712 Wedge flow meters are commonly used to measure flow in pipes by creating a flow rate dependent pressure drop across a restriction.
randki myszków The relationship between pressure drop and flow rate not only depends on the geometry of the wedge, but also on the Reynolds number of the flow and the pipe geometry immediately upstream and downstream of the wedge.
Using Computational Fluid Dynamics (CFD), Simphysics assisted a client to investigate the dynamic pressure loss factor of such a device. The CFD predicted pressure drop agreed with physical test data to within the error bounds of the data.
Not only did the CFD results provide the client with insightful visualisation of the flow, but the client was then able to investigate alternative wedge geometries and upstream / downstream pipe configurations in a very cost effective manner.
