Strong Flows of Viscoelastic Wormlike Micelle Solutions
The unique rheological properties of viscoelastic wormlike micelle solutions have led to their broad use as rheological modifiers in consumer products such as paints, detergents, pharmaceuticals, lubricants and emulsifiers. In addition, micelle solutions have also become increasingly important in a wide range of industrial and commercial applications including agrochemical spraying, inkjet prin...
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 کاملFilament stretching and capillary breakup extensional rheometry measurements of viscoelastic wormlike micelle solutions
filament stretching extensional rheometer and capillary breakup extensional rheometer are used o measure the extensional rheology of a series of wormlike micelle solutions experiencing a niaxial elongational flow. The experiments are performed using a series of wormlike micelle olutions of both cetylpyridinium chloride and sodium salicylate NaSal in an aqueous sodium hloride solution and cetylt...
متن کاملViscoelastic flow past a confined cylinder of a polyisobutylene solution
Viscoelastic constitutive equations are evaluated using the benchmark problem of the planar flow past a confined cylinder for a well-characterized solution of S%(w/w) polyisobutylene in tetradecane. The ratio of channel height to cylinder diameter is equal to two. We compare finite element simulations with point-wise measured velocities and stresses obtained by means of laser Doppler anemometry...
متن کاملThe Faraday instability in wormlike micelle solutions
The behaviour of semi-dilute wormlike micelle solutions under vertical vibrations is investigated using classical measurements of the Faraday instability threshold along with two new experiments based on particle imaging velocimetry and birefringence. We provide evidence for the presence of oscillations of the critical acceleration and wave number with the vibration frequency, which are linked ...
