In the present paper both steady and unsteady CFD analysis were performed to investigate flow behavior in a bulb turbine. A study was carried out assess effect of runner tip hub gap size on turbine performance. Also special attention paid power break off at full load condition as well hysteresis phenomena efficiency curve occurring same region. The calculations only for some operating points interest near numerical results compared with experimental data from BulbT project.
The processing and properties of chromium–molybdenum, powder metallurgy steels with admixed extra-fine nickel (XF Ni) were investigated. Prealloyed Fe–1·5Cr–0·2Mo was blended different quantities XF Ni, while a hybrid steel lower Cr content prepared by blending Fe–0·5Mo prealloyed powders, additions Ni copper powders. These compacted into part shapes in order to evaluate the effect thickness on sinterhardening behaviour. parts also subjected cooling rates after sintering. This study showed...
This report highlights the results of a project carried out at National Research Council Canada (NRC), with overall objective to address major issues Li-air battery technology and assemble multi-electrode pilot-scale prototype. Several innovative ideas technologies were investigated along core concept polymer-based solid-state technology. The assessment is discussed through as well other sources, especially concerning its readiness perspectives for automotive applications.
This paper addresses an important issue for the practical application of lithium ion batteries in PHEV.

A concept of reactive hot spots intruded in a thick, structural material casing was investigated to generate fine fragments for efficient energy release from under explosive loading. This achieved through distributing micro MoO3 particles into granular Al casing, made by isostatic pressing, fuel-rich ratio 10Al+MoO3. Reaction and during primary or secondary fragmentation creates heat gas products form micro-scale spots, whose expansion initiates local fractures leading the rest Al. Explosion...

Abstract Predicting fluid-structure interaction phenomena is an ongoing challenge in numerical simulations. While we look for fast algorithms to solve the equations, some problems need a high accuracy order correctly predict results. Hence, controlling every aspect of algorithm gives possibility optimise specific parts, potentially leading greater accuracy. Developing such methodology can be achieved on open source software as OpenFOAM.
It is becoming increasingly common for Francis machines to operate at no load and low conditions compensate the variation in energy production of other renewable sources, such as solar wind.These are characterized by various flow phenomena presence large backflow regions, cavitation volumes, interblade vortices, and, some cases, vaneless space vortices.All these responsible increasing pressure pulsations consequently, dynamic stresses, which can significantly affect fatigue lifespan...
