- Slurry Transport Fundamentals, A Historical Overview & The Delft Head Loss & Limit Deposit Velocity Framework by Sape Miedema, edited by Robert Ramsdell is a comprehensive overview of slurry transport and presents the DHLLDV framework. This framework is a model of slurry transport incorporating all the different regimes, from homogeneous (for small particles and high velocity), to heterogeneous (for medium-sized particles), and stratified (sliding or fixed bed, for coarse particles and low velocities) transport. In addition, it gives an overview of a number of other models in common use, including Durand & Condolios, Furboter, Jufin & Lopatin, Wasp, Wilson/GIW, and SRC.
- DHLLDV Software: Open source software (written in Python) implemeting the DHLLDV Framework.
- DHLLDV Excel Workbook: A spreadsheet implementing the DHLLDV framework, a pump model for evaluating slurry transport systems, and some of the other models for comparison.
- An Overview of Flow Regimes Describing Slurry Transport: In slurry transport we talk of flow regimes defined by the physical mechanisms transporting the solids and the distribution of the solids in the pipe. The various models of slurry transport present mathematical equations describing the process, that are generally calibrated using the available experimental data. However, the physics of the various regimes vary with particle and pipe diameter, concentration and fluid properties, and some regimes may not be available in some scenarios. This paper describes 9 flow regimes and 6 scenarios, 3 based on a constant volumetric spatial concentration (usually in a laboratory) and 3 based on a constant volumetric transport concentration (usually in real life). The flow regimes present in each scenario are explained and examples of experiments are given.
