Investigation of Newtonian Fluid Flow through a Two- dimensional Sudden Expansion and Sudden Contraction Flow Passage
–The importance of flow through sudden change in flow passages lies in the numerous industrial applications such as, polymer processing, injection molding, biomedical instruments, extrusion, thermoforming etc. In this work, fluid flow through an axi-symmetric sudden contraction flow passages has been carried out using commercial CFD tools. Flow in the inverse direction, which represents flow th...
متن کاملDroplet Breakup in Expansion-contraction Microchannels
We investigate the influences of expansion-contraction microchannels on droplet breakup in capillary microfluidic devices. With variations in channel dimension, local shear stresses at the injection nozzle and focusing orifice vary, significantly impacting flow behavior including droplet breakup locations and breakup modes. We observe transition of droplet breakup location from focusing orifice...

15 صفحه اولPhysical Modelling of Self-Aeration in a Cavitating Sudden PIPE Expansion Flow
Sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. The complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. This paper focuses on aeration in sudden pipe expans...
متن کاملModeling gas flow through microchannels and nanopores
Microchannel based systems have emerged as a critical design trend in development of precise control and maneuvering of small devices. In microelectronics, space propulsion and biomedical areas, these systems are especially useful. Nanoscale pores are recently becoming of great interest due to their beneficial drag and heat transfer properties. However it is difficult to predict the flow perfor...
