Laminar flow of a viscoelastic shear-thinning liquid through a plane sudden expansion preceded by a gradual contraction
Experimental observations are reported for the laminar flow of a viscoelastic liquid through a symmetrical plane sudden expansion preceded by a gradual contraction from a square duct. As is well known, for Newtonian fluid flow above a critical Reynolds number the flowfield downstream of an expansion becomes asymmetric. For the viscoelastic liquid investigated here the asymmetry is greatly reduc...
متن کاملTurbulent flow through a plane sudden expansion
The results are reported of an experimental investigation of turbulent flow through a plane sudden expansion of expansion ratio R=D/d=4 and aspect ratio A= w/h=5.33. It is well known that plane sudden expansions with R greater than 1.5 produce asymmetric flows and this was again seen in this study. The literature for the asymmetric situation (R>1.5) is surprisingly limited and only axial veloci...
متن کاملInvestigation 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 کاملA viscoelastic model of shear-induced hemolysis in laminar flow.
We present measurements of human blood hemolysis caused by laminar shear stresses ranging from 50 to 500 Pa for exposure times extending from 60 to 300 s using a Taylor-Couette device. A viscoelastic model is proposed that captures the response of the red blood cells to shear stress. The model is based on well-established mechanical properties of the red blood cell membrane, and shows good agre...
متن کاملDynamic and Deformation of a liquid Droplet in a Convective Two-Dimensional Laminar Flow
The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...
