1. Aeroengine transients in altitude test facility
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. LÄS MER
2. Greenhouse gas emissions from three large lakes during the autumn 2020
Kandidat-uppsats, Linköpings universitet/Institutionen för temaSammanfattning : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. LÄS MER
3. Optimering av kompressorstyrning : För kostnadseffektivare styrning av multipla kompressorer i ett tryckluftssystem
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktionSammanfattning : För att skapa konkurrenskraft krävs alltid optimering, av flera olika processer, mot mer energi- och kostnads-effektivitet. Anläggningen som används i detta projekt, ett kraftvärmeverk som byggdes så sent som 2015, har dragits med vad som verkat vara en icke optimal drift av tryckluftssystemet med tre identiska, frekvensomformarstyrda kompressorer.

4. CFD and Experimental Study of Refuelling and Venting a Fuel System
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : In 1999, California Air Resources Board (CARB) implemented a regulation that required all gasoline cars sold in California be fitted with an Onboard Refueling Vapor Recovery System (ORVR). The ORVR system is designed to prevent Volatile Organic Compounds (VOCs) from escaping into the atmosphere during refuelling by storing the gas vapours in a carbon canister. LÄS MER
