1. 16. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

   Författare :Axel Barrdahl; [2022]
   Nyckelord :Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

   Sammanfattning : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. LÄS MER

3. 17. Glued connection for TCC slabs : Experimental and Numerical investigation

   Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Ervin Halilovic; Seid Lotinac; [2022]
   Nyckelord :TCC connection; Composite element; Adhesive connection; Silicone Adhesive; Polyurethane Adhesive; Slip modulus; Shear stress; Cohesive elements; Traction seperation law; Mullins effect; Hysteresis;

   Sammanfattning : Timber-concrete composite (TCC) structures are becoming more popular in several industrial applications as an efficient method for optimizing the structural performance and the cost of construction as well as lowering the emissions of carbon dioxide. TCC floors are more sustainable than pure concrete floors and more resistant to vibrations and excessive deflections than pure wooden floors. LÄS MER

4. 18. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Rosalie Johnsson; Lilian Asiegbu; [2022]
   Nyckelord :gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

   Sammanfattning : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. LÄS MER

5. 19. Strengthening of non-composite bridges by Partial Composite Action

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Johan Tjernberg; [2022]
   Nyckelord :Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

   Sammanfattning : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

7. 20. Rheology of dense particle suspensions in linear over-damped flow

   Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

   Författare :Salar Zamani Salimi; [2021]
   Nyckelord :;

   Sammanfattning : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.
