Hydrodynamics of the mixing chamber in RIM: PIV flow-field characterization

The flow-field in a Reaction Injection Moulding, RIM, machine mixing chamber was characterized using the Particle Image Velocimetry (PIV) technique. This study covered the industrial range of Reynolds numbers, Re, for the RIM process, from 100 to 500, setting the overall trends of the flow-field in...

Description
Summary:The flow-field in a Reaction Injection Moulding, RIM, machine mixing chamber was characterized using the Particle Image Velocimetry (PIV) technique. This study covered the industrial range of Reynolds numbers, Re, for the RIM process, from 100 to 500, setting the overall trends of the flow-field in that range, with particular focus on the flow regime transition range of 100
