Characterization of the Effects of Jet Radial Position on Entrainment Ratio in a Subsonic Ejector

The work investigated an ejector-based intake, the Atlantis Intake System (AIS), in static conditions. A control volume (CV) analysis was presented and used to estimate the entrainment ratios of the AIS. The CV analysis also estimated momentum loss due to the jet’s interaction with the mixing chamber walls. An experimental campaign was performed to validate the CV analysis. Pressure and entrainment ratios were experimentally determined for an AIS in a concentric alignment. Secondly, entrainment ratios were recorded for changing lateral positions of the primary tube. This work showed that the entrainment ratio was insensitive to lateral displacement within normalized radial position less than 0.60. For normalized radial positions beyond 0.6, a sharp drop in the entrainment ratio occurred. A maximum of 18% loss in entrainment ratio was measured. This work shows that there is a minimal penalty to entrainment ratio for small offsets of the primary jet and has the potential to simplify ejector and AIS design

Pipeline Control System Applications Targeting Business Objectives

Today’s increasingly competitive markets require new levels of reliability, flexibility and cost performance from gas transmission pipelines. One method that pipeline companies can use to address these business objectives is to target station and turbomachinery control system design specification, retrofits and integration."/jats:p" "jats:p"State of the art control tools and technologies have placed turbomachinery control engineering within the grasp of the end users. NOVA Gas Transmission Ltd. (NGTL) has taken advantage of this to specify, design, and implement integrated control systems that best address their business needs."/jats:p" "jats:p"This paper explores the end user perspective on applying control system technology to both new and existing compressor stations. The specification of new units and control retrofits are described. The resulting increase in system reliability and flexibility, and reduced maintenance costs is also presented

Geospatial Data Analysis and Economic Evaluation of Companies for Sustainable Business Development—An Interdisciplinary Teaching Approach

Sustainable business development is connected with environmental impact, natural resources and people. This makes the location a crucial factor for the operation of a business. Therefore, a combination of both geo-spatial data analysis and traditional economic evaluation of companies are advantageous. The consideration of geolocation is beneficial with calculations for process optimizations and cost efficiency as well as ecological and social compliance. Since integrating geospatial methods into economics is a rather new interdisciplinary approach, it seems necessary to establish innovative teaching concepts for the education of experts in this field. Creating and testing such new teaching concepts based on playful learning is the idea behind the ERASMUS+ project SPATIONOMY (“Spatial exploration of economic data—methods of interdisciplinary analytics”). An interdisciplinary team of teachers educates an interdisciplinary assembled group of international students. Hence, the fields of economics/business informatics and geography/geomatics are represented by participants and staff. Based on initial lessons about basic knowledge in the connected subjects, the central elements of the teaching concept are case studies and a simulation game, each with interdisciplinary challenges. The principal aim of the project—to educate students to become specialists in spatial economics—could be achieved. This paper aims to present, evaluate and discuss the methodological approach as well as the results from the application of the simulation game. The results show that the gamification of education is worthy. Simulation game-based learning appears to be more playful and experiential compared to traditional teaching approaches. Further research in this area should focus on the students’ engagement evaluation and attitude towards sustainable behaviour in their own business
