It is shownthat, based on a natural scaling law for the viscosity, a simple solution can be found forquantities such as the Hubble parameter and the energy density. Analysis assists in design of flow systems for petroleum, coal, polymers, and other materials.ĭirectory of Open Access Journals (Sweden)įull Text Available A bulk viscosity is introduced in the formalism of modified gravity. Fluid is taken to be viscous, non-Newtonian, and incompressible the gas to be ideal the flow to be inertia-free, isothermal, and one dimensional. Reduced viscosity interpreted for fluid/gas mixturesĪnalysis predicts decrease in fluid viscosity by comparing pressure profile of fluid/gas mixture with that of power-law fluid. • With this function the rotation of particles are described correctly. • This correction is function of the hydrodynamic concentration of particles. ![]() • Coincidence of curves requires a correction of value of viscosity in calculations. ![]() Highlights: • Dynamic susceptibility was measured at different temperatures and concentrations. The value of the correction coefficient doesn’t depend on temperature and is the universal function of the hydrodynamic concentration of particles. Coincidence of normalized dynamic susceptibility curves plotted for different concentrations was obtained only after introducing correction for the value of dynamic viscosity of the magnetic fluid. Lebedev, A.V., E-mail: frequency dependences of dynamic susceptibility were measured for a series of magnetic fluid samples with the same dispersed composition at different temperatures. Viscosity of magnetic fluids must be modified in calculations of dynamic susceptibilityĮnergy Technology Data Exchange (ETDEWEB)
