... Abstract This study presents an investigation of some performance parameters and emissions characteristics of a six-cylinder submarine diesel engine operated on blends of biodiesel produced from waste vegetable oil (WVO). A heterogeneous catalyst was developed from waste eggshells via...

... and discharge passages of pump system was made with CFD numeric simulation. Two sets of new S-shaped, façade and plane, shaft extension tubular pump were developed. A physical model experimental research on energy performance, cavitation performance and runaway characteristics of the pump model system has been...

.... In particular, to evaluate the performance of MORET for local flux or power density calculations in full size reactor cores, it has been decided to contribute to the computational benchmark proposed by Dr. Hoogenboom and Dr. Martin at the ANS M&C 2009 conference. The aim of this benchmark is to monitor...

... control adjustments and accompanying field performance tests just to verify a single specified operating point. A methodology is proposed in this paper for which it is postulated that only a single field test point needs to be obtained within a flow-pressure target window of ±3% of the specified flow...

.... Significant thermal efficiency improvement can be achieved by increasing the high side cycle pressure. Recompression Rankine cycle can be a potential alternative with proper design measures taken to avoid toxicity and flammability. Keywords: Ammonia, Rankine cycle, heat sources, analysis, performance...

... 04 05 2009 The optimisation of engine performance by predictive means can help save cost and reduce environmental pollution. This can be achieved by developing a performance model which depicts the operating conditions of a given engine. Such models can also be used for diagnostic...

.... With fans, it is now commonplace to put performance guarantees in place when purchasing new equipment which specify volume flow, pressure requirements and expectations for efficiency or power that have to be met. Test procedures suitable for conducting fan performance guarantee tests are available in many...

... 28 10 2008 With few exceptions, fan vendors do not normally provide a written guarantee for the aerodynamic performance of a fan or even identify tolerances for the rated performance. When requested, the vendor often refers to acceptance criteria established in accordance with fan...
