Re: Hydraulic pump -3d simulation paper
(1). Figure 6.28 Eta vs Q shows clearly the difference between the idealized model and the real world data. (2). In real world, the flow is always 3-D turbulent, and most likely transient. At the design point (or BEP), the flow is less complicated and thus a better match is achieved. At the off-design point, the loss model is not accurate because the base model is very complicate. (3). The value of the paper is in its careful approach in numerical modelling, comparison with experimental data, and the identification of the differences.
