摘要

The present work involves detailed nondimensional study of density-matched viscosity-stratified flow at various viscosity ratio (η) and Reynolds number. For fully-developed flow with increasing η, it is found that the maximum U-velocity (U max), and pressure gradient increases whereas interface height decreases monotonically. For developing flow, it is shown that the U max increases whereas the interface height decreases asymptotically along the axial direction. However, the increase and decrease is more for square duct as compared to the plane channel. Furthermore, a set of development-length correlations are proposed for the plane channel. The present results can be used for the efficient transportation of a more viscous fluid.View full textDownload full textRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10407782.2011.600580
