1. 1. Evaluating a new hydraulic implementation in LPJ-GUESS for three sites in north Europe

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Carl Holmquist; [2023]
   Keywords : Physical Geography and Ecosystem analysis; LPJ-GUESS; drought; sensitivity analysis; evapotranspiration; gross primary production; hydraulic parameters; boreal forest.; Earth and Environmental Sciences;

   Abstract : Drought is projected to increase in frequency and intensity and impacts trees with increased water stress and increased mortality rate. Water stresses can cause hydraulic failure-related mortality or carbon starvation due to tree species having different strategies to deal with water stresses. READ MORE

3. 2. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Eddie Blomström; [2022]
   Keywords : fishway; flow; hydraulics; HEC-RAS;

   Abstract : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. READ MORE

4. 3. Two-phase CFD Modelling and Validation : SH204X Master Thesis Project Report

   University essay from KTH/Kärnenergiteknik

   Author : Richard Härlin; [2022]
   Keywords : Master Thesis; Simulation; Validation; DEBORA; CFD; OpenFOAM; Boiling; Two-phase Thermal-Hydraulics; Fluid Mechanics; Nuclear Power Safety; Examensarbete; Simulering; Validering; DEBORA; CFD; OpenFOAM; Kokning; Tvåfas Termohydraulik; Kärnkraftssäkerhet;

   Abstract : This project deals with two-phase CFD model validation, a subject which is currently under active research due to its complexity. The goal is to create a model that predicts data profiles to an acceptable degree for a wide array of flow conditions. The applications within the nuclear field would mainly be for safety analysis, e.g. READ MORE

5. 4. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

   University essay from Lunds universitet/Teknisk geologi

   Author : Simon Kreipl; [2021]
   Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

   Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

6. 5. Modelling and improvement of 2-Speed Smoothing System

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Oskar Nilsson; [2021]
   Keywords : Simulink; Skid-steer; Hydraulics;

   Abstract : A skid steer loader is a machine used in construction for multiple tasks. Its small size and versatility makesit a use-full addition to any work site. The machine is driven by a combustion engine that in turn powers ahydraulic pump. This hydraulic fluid from the pump is then directed to either motor to propel the vehicle. READ MORE
