1. 36. Boundary conditions in left ventricle for simulating mitral valve regurgitation

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Théo Cyril Arvid Monpouet Ekeram; Ellen Mattsson; [2023]
   Nyckelord :;

   Sammanfattning : Since various kinds of cardiovascular diseases are the leading cause of death today, it is of great importance to further our understanding of not only the diseases themselves, but also different treatments. One of the emerging tools is computational fluid dynamics. LÄS MER

3. 37. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

   Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Annachiara Nardone; [2023]
   Nyckelord :tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

   Sammanfattning : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. LÄS MER

4. 38. BLOOD FLOW DYNAMICS IN IDEALIZED MODEL OF LEFT ATRIUM USING FINITE ELEMENT ANALYSIS

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Marwin Haddad; Yonatan Noel Efrem; [2023]
   Nyckelord :finite element analysis; fluid mechanics; blood flow dynamics; cardiovascular anatomy;

   Sammanfattning : Cardiovascular diseases, including heart failure, are a global health concern, necessitating advancements in non-invasive diagnostic tools and treatments. Computational modeling offers an invaluable approach to simulate and understand the intricacies of cardiac flow dynamics. LÄS MER

5. 39. CFD Analysis of the Flow Around a Paraglider Wing

   Master-uppsats, KTH/Teknisk mekanik

   Författare :Caterina Gennari; [2023]
   Nyckelord :Paraglider Wing; CFD; RANS; DES; Aerodynamics; Aerodynamic Hysteresis; FSI; Deformable Structure; Membrane; Shell Elements;

   Sammanfattning : In this study, the characteristics of the flow around a paraglider wing were investigated through the use of Computational Fluid Dynamics (CFD) simulations by solving both Reynolds Averaged Navier-Stokes equations and Delayed Detached Eddy Simulations were employed. This allowed the observation of how the unique shape of the canopy of a paraglider can influence the behaviour of the flow and how aerodynamic hysteresis can manifest on this sort of wing. LÄS MER

7. 40. A Continuous-time ODE Framework to Centrality in Dynamic Networks

   Kandidat-uppsats, Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

   Författare :Francisco Garcia Atienza; [2023]
   Nyckelord :networks; centrality; continuous-time; matrix logarithm; ode framework; katz; resolvent; Mathematics and Statistics;

   Sammanfattning : The present study discusses and evaluates a novel continuous-time approach to network centrality, a fundamental concept in network analysis. Static methods based on discrete snapshots or time slices for measuring node interaction in networks that change over time do not fully capture the dynamical nature of network evolution. LÄS MER
