Abstract:
An open-source computational fluid dynamics(CFD)code named OpenFOAM is used to validate the flow field characteristics(flow patterns and pressure drop)around a single cylinder.Results show that OpenFOAM is suitable for simulating the low Reynolds number flow and Shaw’s analytical expression is one of the solutions to Stokes’ paradox.Experiments are performed on fibrous media and OpenFOAM simulation is carried out using the Tronville-Rivers two-dimensional random fiber model in terms of the characteristics of pressure drop.It is shown that the Kuwabara model predicts the pressure drop of fibrous filter media more accurately than the Happel model, and the experimental pressure drop is between simulated pressure drops with both non-slip and full-slip boundaries on fiber surfaces.
