Abstract In this article, a numerical investigation of the effect miniaturized five-hole probe downstream transonic low-pressure turbine vane row is presented. First, calibration was performed in uniform flow conditions, as case for any traditional calibration, wide range Mach number, yaw angle, and pitch angle conditions. The on general field throughout segments then evaluated by performing co...

A graph on 2n vertices can be Skolem-labeled if the vertices can be given labels from {1, . . . , n} such that each label i is assigned to exactly two vertices and these vertices are at distance i. Mendelsohn and Shalaby have characterized the Skolem-labeled paths, cycles and windmills (of fixed vane length). In this paper, we obtain necessary conditions for the Skolem-labeling of generalized k...

The study of unsteady aerodynamic phenomena in wind tunnels is supported by gust-generating devices capable generating adjustable magnitude and periodicity velocity fluctuations a flowfield. Gusts are typically generated actively introducing moving vanes to direct the flow, or passively tailoring boundary layer growth shape tunnel. flow facility used here student-built closed-return low-speed t...

The flat-hull ship design is an innovative concept that saves costs and speed-up the fabrication of ship. Even though was hydrodynamically inefficient, some shipowners probably experienced issue with its unusual shape disadvantages where drag greater than conventional ships. This paper aimed to improve a vessel using hull vane bow foil reduce resistance. asymmetric NACA 4412 0012 were used for ...

In this study, we have investigated variations in the potential of floating and submerged leaves of longleaf pondweed (Potamogeton nodosus) to withstand silver ion (Ag+)-toxicity. Both floating and submerged leaves changed clear colorless AgNO3 solutions to colloidal brown in the presence of light. Transmission electron microscopy revealed the presence of distinct crystalline Ag-nanoparticles (...

In this paper, submerged vanes were placed at the upstream area of a bridge pier located at the 90 degree angle. Then, using the laboratory equipment, a study of flow pattern was conducted throughout the bend, specifically around the pier and submerged vanes. ADV velocimeter was incorporated in order to help measure 3D velocity components. Submerged vanes were installed at distances of 40 and 6...

Submerged macrophyte communities are frequently subjected to disturbance of various frequency and strength. However, there is still little experimental evidence on how mechanical disturbance affects the performance and species composition of such plant communities. In a greenhouse experiment, we constructed wetland communities consisting of five co-occurring clonal submerged macrophyte species ...
