1. 11. Fault current injection from Inverter Based Generation in the distribution grid : A case study of distribution grid on the Swedish island of Gotland

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Farsad Mansori; [2022]
   Keywords : Distribution generator; Inverter-Based Distributed Generation; Inverter Based Generation; DFIG; PSCAD; Distribution grid; Overcurrent protection;

   Abstract : This work proposes recommendations for new guidelines for fault current injection on a distribution grid. These guidelines will help improve the transition towards renewable electrical energy generation. READ MORE

3. 12. Artificial Neural Network in Exhaust Temperature Modelling : Viability of ANN Usage in Gasoline Engine Modelling

   University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

   Author : Musa Nibras; Roos Linus; [2022]
   Keywords : Artificial Neural Network; Data-driven Modelling; Engine Modelling; Transient behaviour; Static behaviour; Feed Forward Network; Layer Recurrent Network; NARX; Long Short Term Memory; Gated Recurrent Network; Data processing;

   Abstract : Developing and improving upon a good empirical model for an engine can be time-consuming and costly. The goal of this thesis has been to evaluate data-driven modelling, specifically neural networks, to see how well it can handle training for some static models like the mass flow of air into the cylinder, mean effective pressure and pump mean effective pressure but also for transient modelling, specifically the exhaust gas temperature.

4. 13. Development of CFD method to model thermal properties of laminates in a truck cab : Modeling solids and HVAC performance

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Aniruddh Mohan; [2022]
   Keywords : CFD; Conjugate heat transfer; HVAC; Shell modeling;

   Abstract : The study of Heating, Ventilation and Air Conditioning (HVAC) system performance is important to understand its energy consumption, especially for electric vehicles. The purpose of this thesis is to develop a methodology to simulate the flow within the Scania S20H cab while also capturing the thermal properties of the fluid and solids within the cab. READ MORE

5. 14. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Matilda Tiberg; [2022]
   Keywords : Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

   Abstract : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. READ MORE

6. 15. Aeroengine transients in altitude test facility

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Baptiste VILLENEUVE; [2022]
   Keywords : ;

   Abstract : 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. READ MORE
