1. 1. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Andreas Lilja; [2020]
   Keywords : CFD; FDS; FEM; TASEF; EKS; Eurocode; Simulation; Fire; Balcony; CFD; FDS; FEM; TASEF; EKS; Eurokoderna; Simulering; Brand; Balkong;

   Abstract : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. READ MORE

3. 2. Investigation of open-Source CFD software on shipyards - Analysis of combustion outlets on large yachts using openFoam®

   University essay from

   Author : Carl Jascha Mordhorst; [2019-07-03T12:39:50Z 2019-07-03T12:39:50Z 2011]
   Keywords : Transport; Farkostteknik; Transport; Vehicle Engineering;

   Abstract : Abstract Modern engineering requires detailed knowledge of forces, flow directions and velocities, when designing the vehicles of the future. In the ship building industry this is traditionally done in towing tank and wind tunnel experiments or by the long experience of skilled engineers. READ MORE

4. 3. k-ε turbulence modeling for a wind turbine : Comparison of RANS simulations with ECN wind turbine test site Wieringermeer (EWTW) measurements

   University essay from KTH/Kraft- och värmeteknologi

   Author : ERMAN EREK; [2011]
   Keywords : wind energy; turbulence modeling;

   Abstract : In this report we discuss the use of k-ε RANS (Reynolds-averaged Navier-Stokes equations) turbulence model for wind turbine applications. This model has been implemented in the new wind turbine wake CFD code that is being developed at ECN. READ MORE

5. 4. Estimating Erosion in Oil and Gas Pipe Line Due to Sand Presence

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Akar Abdulla; [2011]
   Keywords : CFD; Erosion; Solid particle impact; Multiphase flow ; Turbulence.;

   Abstract : Transporting solid particles in oil and gas flow cause erosion damage to the pipeline and fittings. The aim of this thesis is to study the effect of impact velocity on the erosion damage in 90 degree long elbow by using two different erosion models namely, Oka model and E/CRC model. READ MORE

6. 5. Developing boundary conditions usingthe nesting technique on simple terrain : A study of wind and turbulence intensity proles sensitivity

   University essay from Institutionen för kultur, energi och miljö

   Author : Raphael Desilets-Aube; [2011]
   Keywords : Lillgrund; turbulence intensity; WindSim; case study; actuator disc model; roughness length; boundary conditions;

   Abstract : As wind industry is developing steadily oshore, the wind turbine spacing remainsa key element for maximizing revenues and reducing loading from turbineswake interaction. In the case of relatively close to shore oshore wind farms, orlarge arrays onshore, the turbulence intensity coming from dierent sectors canhave an eect on wake growth and decay. READ MORE
