Exponential formula for computing effective viscosity. Powder Technology, 129(1-3), 156–160. | Series/Report no.: | Powder technology | Abstract: | An exponential model is proposed for evaluating the effective viscosity of a particle-fluid mixture. First, theoretical consideration is restricted to the dilute condition without effects of dynamic particle interactions and fluid turbulence. This leads to a power series expressed in terms of particle concentration, which can be viewed as an extension of the Einstein's formula. The derivation is then extended using an exponential model for the condition of high particle concentrations. The exponential formula obtained, which is not subjected to the maximum particle concentration, is found comparable to various empirical formulas available in the literature | URI: | https://hdl.handle.net/10356/94067 http://hdl.handle.net/10220/7676 |
