1. 1. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Daiki Makii; [2020]
   Keywords : Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

   Abstract : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

3. 2. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : David Bennich; [2020]
   Keywords : reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

   Abstract : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. READ MORE

4. 3. Development and application of a multidomaindynamic model for direct steamgeneration solar power plant

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

   Author : Anthony Rousset; [2017]
   Keywords : Concentrated Solar Power CSP ; Direct Steam Generation DSG ; dynamic modelling; co-simulation; thermal-hydraulic calculation; two-phase flow; Ledinegg instabilities; control-command; regulation; PID controller.; Koncentrerad solenergi CSP ; Direkt ånggenerering DSG ; dynamisk modellering; co-simulering; termisk hydraulisk beräkning; tvåfasflöde; Ledinegg instabiliteter; kontrollkommando; reglering; PID-kontroller..;

   Abstract : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies.

5. 4. Influence of gas sparging on membrane performance

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sandra Farran-Lee; [2015]
   Keywords : chemical engineering; kemiteknik; Technology and Engineering;

   Abstract : A new oxygen barrier film that is made of arabinoxylan has been developed by the company Xylophane. Arabinoxylan is available among other things in wheat bran. But a problem with the method of extracting the arabinoxylan is that after an alkali extraction is ultrafiltration used to remove impurities and the flux during this is quite low. READ MORE

6. 5. Experimental Investigation of two-phase flow in microchannels. Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ali Ammari; [2012]
   Keywords : ;

   Abstract : For ammonia-water absorption refrigeration technology it is suggested to use bubble type absorbers because the higher contact surface area provides a higher mass transfer rate. Furthermore, dispersion of bubbles in the bulk of liquid phase also exhibits better heat transfer characteristics that facilitate the recovery of dissipated heat of the exothermic absorption.
