Analytical solutions of compacting flow past a sphere
A series of analytical solutions are presented for viscous compacting flow past a rigid impermeable sphere. The sphere is surrounded by a two-phase medium consisting of a viscously deformable solid matrix skeleton through which a low viscosity liquid melt can percolate. The flow of the two-phase medium is described by McKenzie’s compaction equations which combine Darcy flow of the liquid melt w...
متن کاملFlow of a wormlike micelle solution past a falling sphere
With the increasing use of wormlike micelle solutions as rheological modifiers in many consumer products, the prediction of the behavior of these fluids has grown increasingly important in recent years. In this paper, the flow past a sphere falling at its terminal velocity through a column of a wormlike micelle solution is experimentally studied. The working fluid is an entangled wormlike micel...
متن کاملThree Dimensional Analysis of Flow Past a Solid-Sphere at Low Reynolds Numbers with the Aid of Body Fitted Coordinates
In this paper, the flow-field of an incompressible viscous flow past a solid-sphere at low Reynolds numbers (up to 270) is investigated numerically. In order to extend the capabilities of the finite volume method, the boundary (body) fitted coordinates (BFC) method is used. Transformation of the partial differential equations to algebraic relations is based on the finite-volume method with coll...

متن کاملAdaptive simulation of the sub - critical flow past a sphere
Adaptive DNS/LES is used to compute the drag coefficient cD for the flow past a sphere at Reynolds number Re = 10. Using less than 10 mesh points, cD is computed to an accuracy of a few percent corresponding to experimental precision, which is at least an order of magnitude cheaper than standard non-adaptive Large Eddy Simulation LES computations in the literature. Adaptive DNS/LES is a General...
