摘要：

This paper presents ongoing work at Australia's largest paper recycler, Visy Pulp & Paper, involving experimental and computational fluid dynamics (CFD) studies to understand paper pulp mixing processes, aimed at identifying means of reducing the large power consumption of the agitators currently used. The key focus of this paper is on the modelling of a pseudo-plastic fluid and the determination of means by which adequate flow circulation can be maintained in such a system. We look at reducing the present agitator speed, at using a larger impeller, and examine the performance of a completely different design. Power consumption reductions of 50%, and perhaps 75-80%, from present levels, appear feasible and could be implemented economically.
