Hydraulic energy recovery by replacing a control valve with a centrifugal pump used as a turbine
(2016)
Reverse running centrifugal pumps as turbines (PaT’s) are used in small-scale hydropower generation mainly because of lower investment costs. Predicting the turbine mode operation point for a centrifugal pump has a lot of ...
Design of noise reduction cavity structures for additive manufacturing
(2016)
Passive acoustic mufflers have a vital role in controlling the transmission of airborne noise passing into the human living environment. The geometry of the air path affects the attenuation of sound due to absorption and ...
Fan system monitoring via cloud service
(2016)
The majority of electricity consumption in industrial and service sectors in the European Union is caused by electric motors, largely by fluid handling systems such as fans, pumps, and compressors. By utilising energy ...
Vähähiilisen asumisen kehittäminen käyttäjän näkökulmasta
(2016)
Asumisen osuus Suomen vuosittaisista kasvihuonekaasupäästöistä on noin 15 %, joten myös kuluttajilla on merkittävä rooli tavoiteltaessa ilmastonmuutoksen hillitsemiseksi tarvittavia päästövähenemiä. Tässä diplomityössä ...
The MENA and North America super grid towards 100% renewable energy power supply by 2030, with specific focus on Iran as a case study and compressed air energy storage as a storage technology
(2016)
The main objective of this thesis is to analyze a 100% renewable energy (RE)-based system for the MENA region and North America in an hourly resolution model for the year 2030 and to evaluate their results from different ...
Enhancing the 3-dimensional forming of paperboard with modelling and simulation
(2016)
This thesis work was based on the enhancing of 3-dimensional forming of paperboard tray package by adopting line creasing pattern and analysis of the results with the help of mathematical modelling and simulation. The aim ...
Tulevaisuuden energiatehokas teollisuuspuisto
(2016)
Tutkimuksessa selvitetään uusiutuvien energiateknologioiden soveltumista valmistavan teknologiateollisuuden toimintaan ja teollisuuspuistossa toimimisen tuottamia mahdollisia etuja yritysten energiankäytön osalta. Toimimalla ...
Dynamic model development of adiabatic compressed air energy storage
(2016)
The share of variable renewable energy in electricity generation has seen exponential growth during the recent decades, and due to the heightened pursuit of environmental targets, the trend is to continue with increased ...
Datahubin merkitys jakeluverkonhaltijalle case: Vantaan Energia Sähköverkot Oy
(2016)
Tavoitteena oleva hiilineutraali energiantuotanto muokkaa sähköntuotannosta sykkivämpää ja vaatii kulutuksen sopeutumista siihen. Tämä synnyttää tarpeen kansallisia markkinoita laajemmille sähkön vähittäismarkkinoille ja ...
Systemic costs of renewable energy
(2016)
The EU energy policy targets to reduce the greenhouse gas emission are forcing the energy systems to transform towards carbon-neutrality and increasing energy efficiency. This is to be done through increasing the share of ...
