This article explores the impact of inlet pre-swirl on pressure pulsation in a mixed-flow centrifugal pump through combination numerical simulations and experimental verification. Firstly, pump’s performance was initially determined both calculations experiments. The comparison between them indicated high accuracy method adopted this paper. Next, flow pattern within at various angles carefully ...

The present work considers the turbulent air flow inside an annular high speed rotor-stator cavity opened to the atmosphere at the periphery. The interdisk-spacing is sufficiently large so that the boundary layers developed on each disk are separated and the flow belongs to the regime IV of Daily and Nece (1960). In such a system, the solid body rotation of the core predicted by Batchelor in ca...

The problem emerging from particle coating is how to manufacture particles with just enough material deposited to achive the desired result [1]. Especially in case of functional coatings, the uniformity of coating thickness over the entire particle surface plays an important role. In our study the performance of two bottom spray coaters and the effect of the particle motion on the coating unifo...
