Laminar and turbulent flow of dense kaolin and ash hydromixtures.
Result description
The concentrated fine-grained slurries can be approximated by rheological models for laminar flow regime, for turbulent flow regime two models based on rheological parameters (Wilson, Slatter) were analysed. The flow behaviour of kaolin and ash slurrieswere experimentally investigated on tube viscometer. It was find out that the flow behaviour index n decreases with increasing concentration, while yield stress ty and fluid consistency K increase with concentration. The both turbulent models can be usedfor prediction of flow behaviour of kaolin and ash slurries in the turbulent regime if the flow behaviour index n is determined from turbulent data.
