Use of Quadratic Model for Modelling of Fly Ash-Water Mixture

Abstract

Novel approach to rheological modelling of a fly ash-water mixture is proposed. The model is first tested against the available experimental data for a corn starch-water, a glass beads-water and a fly ash-water mixture and then used taking the advantage of available CFD code for a calculation of major and minor losses. Numerical results for Quadratic model are compared with results for Power law.
