Summary

The applicability of available computational fluid dynamic codes (CFD) for the calculation of iceslurry flow comes more in focus of current research. Therefore this paper intends to give the results of a literature review about the numerical modelling and available data for the validation. An Overview of previous publications referring to governing equations, modelling approaches is presented. The simulation of isothermal ice-slurry flow is performed as two phase flow in horizontal pipelines for ice mass fractions (0%-50%) and flow velocities (2-5 m/s). The review reveals multiphase models provided by the CFD codes. The validated simulation results show the influence of particles size, volume fraction, phase interactions and granular properties on the radial distribution of concentration profiles. In conclusion, it can be stated, CFD codes are capable to predict satisfactorily the behavior of ice slurry flows in different cases.
