  1. 1. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    University essay from KTH/Tillämpad fysik

    Author : Jonathan Karlsson; [2023]
    Keywords : Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Abstract : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  3. 2. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE

  4. 3. Determining the Acoustic Mobility of Breast Cancer Cells

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Simon Olsson; [2022]
    Keywords : Technology and Engineering;

    Abstract : Breast cancer is one of the most common forms of cancer detected in women. Its heterogeneity and large mutational landscape requires treatment strategies which varies between patients. Triple negative breast cancer (TNBC) is a particularly aggressive subtype which 12-17 \% of breast cancer patient develop. READ MORE

  5. 4. Creative development of lightweight façade constructions in modular housing : The struggle to shut out the noise of the world

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Johan Albihn; [2022]
    Keywords : Acoustical engineering; façade wall construction; modular housing; traffic noise reduction; lightweight construction; industrial design engineering; Akustik; fasadväggkonstruktion; modulhus; reducering av trafikbuller; lättviktskonstruktion; teknisk design;

    Abstract : Modular construction of housing is an industry on the rise. The prefabrication of construction modules gives a greater control over material consumption, promotes standardization, and lessens the disturbance during the construction time in the field. Lindbäcks Bygg AB prefabricates housing modules in their factory at Haraholmen, Piteå. READ MORE

  6. 5. Development of Acoustic Simulations using Parametric CAD Models in COMSOL

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

    Author : Rubén Noya Pozo; Antoine Bouilloux-Lafont; [2019]
    Keywords : parametric CAD models; KBE; acoustic simulations; optimisation; collaboration; MDO; Parametriska CAD modeller; KBE; akustiksimulering; optimering; samarbete; MDO;

    Abstract : With constantly changing regulations on emissions, heavy commercial vehicles manufacturers have to adapt for their products to preserve their quality while meeting these new requirements. Over the past decades, noise emissions have become a great concern and new stricter laws demand companies to decrease their vehicle pass-by noise target values. READ MORE
