Normalization-Based Approach to Electric Motor BVR Related Capacitances Computation
(IEEE, 2019-02-11)
Electrical discharge machining bearing currents that may occur within electric machines of variable-speed-drive motor systems have been recognized for a long time. One key influential factor, the machine's capacitive voltage ...
A framework of disruptive sustainable innovation: an example of the Finnish food system
(Taylor & Francis, 2018-11-26)
Disruptive innovations are perceived necessary for accelerating sustainability transitions. However, it is not always clear what exactly is meant by it, what is to be disrupted, and by whom. Socio-technical transition ...
Numerical analysis on utilizing excess steam for electricity production in cruise ships
(Elsevier Ltd., 2019-02-01)
Marine sector has a significant contribution to the global greenhouse gas emissions and energy usage. Despite that the energy efficiency of ship engines has been increased drastically and the usage of new type of fuels ...
Production and characterization of coffee-pine wood residue briquettes as an alternative fuel for local firing systems in Brazil
(Elsevier, 2019-02-26)
In this work, the production viability, physical, chemical and mechanical properties of briquettes produced from mixtures of coffee shrub residues and pinewood, were evaluated. The densification was carried out under ...
Transition towards 100% renewable power and heat supply for energy intensive economies and severe continental climate conditions: Case for Kazakhstan
(Elsevier, 2019-07-31)
Transition towards 100% renewable energy supply is a challenging aim for many regions in the world. Even in regions with excellent availability of wind and solar resources, such factors as limited availability of flexible ...
Environmental sustainability assessment from planetary boundaries perspective – A case study of an organic sheep farm in Finland
(Elsevier, 2019-06-08)
Food production processes may have both positive and negative environmental sustainability impacts. This makes decision-making challenging in the transition towards more sustainable food production systems. In this paper, ...
Experimental and analytical analysis of vaned savonius turbine performance under different operating conditions
(Elsevier, 2019-05-13)
Global energy production is shifting towards more distributed technologies, where power generation takes place close to people. A vaned Savonius wind turbine is one of the possible solutions, which can fulfil the requirements ...
Feasibility of 100% renewable energy-based electricity production for cities with storage and flexibility
(Elsevier, 2018-11-16)
Renewable energy is expected to constitute a significant proportion of electricity production. Further, the global population is increasingly concentrated in cities. We investigate whether it is possible to cost-effectively ...
Failure of confined granular media due to pullout of an intruder: from force networks to a system wide response
(Royal Society of Chemistry, 2020-07-17)
We investigate computationally the pullout of a spherical intruder initially buried at the bottom of a granular column. The intruder starts to move out of the granular bed once the pulling force reaches a critical value, ...
CFD Modelling of a Centrifugal Compressor with Experimental Validation through Radial Diffuser Static Pressure Measurement
(Hindawi, 2019)
This paper compares experimental static pressure measurement with CFD simulation in a centrifugal compressor at 12 points through the diffuser. Three mass flow rates are selected, each for three operating speeds giving ...
