Vertical axial flow pump device has the characteristics of large and low head, which is widely used in pumping station projects with head 3–9 m. In order to study influence timing effect impeller relative channel guide vane on field pulsation device, whole vertical was taken as research object. The reliability numerical simulation verified by physical model test. pressure inlet outlet regions i...

Based on numerical simulations, the heat transfer and flow field of a turbine vane are analyzed film cooling is improved. The optimization objective increasing overall effectiveness with cascade pressure loss factors staying almost unchanged. Thus, cylindrical holes were replaced by laidback V-crater holes. To analyze effect structural adjustment vane, distributions, mass coefficients investiga...

Droplet breakage is a common phenomenon in converting pipe flow to swirl vane-type separator (VTPS)’ inlet. The evaluation of the dispersed droplet sizes after crucial optimum design inlet structure and estimation oil-water separation performance. This paper studies behavior produced by guiding vanes. Experiments are performed with two different vanes at VTPS. oil droplets downstream measured s...
