    Agrivoltaics in Sweden
    (2025) Antonini, Timothe; Da Corte Vecchino, Filippo; Melkersson, Emil; Merten, Tom; Pettersson, Nathalie; Chalmers tekniska högskola; Chalmers University of Technolog; Albinsson, Bo; Albinsson, Bo
    This report examines the integration of renewable energy into agriculture, focusing on agrivoltaic systems (APVs) that combine photovoltaic (PV) energy generation with farming. It compares Conventional Ground-Mounted Photovoltaics (CGMPVs) and Vertical Bifacial Photovoltaics (VBFPVs) to assess their economic viability and production potential. Additionally, it explores the implications and social acceptance of PV integration in Swedish agriculture, including land-use efficiency, food security, and market dynamics, offering insights for stakeholders seeking sustainable energy solutions in farming.

    A Numerical Study on Aero-Vibro Noise of a Transonic Cavity Flow
    (2025) Kadi, Oliver; Maierhofer, Martin; Serbülent, Berken; Ståhlbom, Oskar; Chalmers tekniska högskola; Chalmers University of Technolog; Yao, Huadong; Yao, Huadong
    This report is part of a project course TRA270 Engineering Fluid-Structure Interactions (FSI) that numerically investigates the Aero-Vibro noise of a transonic cavity. Inspired by previous works this project sets up a numerical solution for this case study. Therefore, the scope of the investigation is limited by several factors, primarily the availability of computational resources and time to the nature of this project being a course. After understanding the fundamentals of FSI, the M219 cavity is meshed using an unstructured trimmed cell mesher with prism layer for the fluid domain. The solid domain was discretized and coupled in STAR-CCM+ using a quadrilateral mesh. The solid-fluid two-way coupled simulation was completed in STAR-CCM+, with mostly standardized solver settings for ideal coupled flows and non-elastic deformation. Sparlart-Allmaras (SA) turbulence model is used because it provides a smaller mesh with faster computing time and provides results comparable to the original report. In addition to investigating a hybrid RANS-LES method, an unsteady RANS (URANS) method was investigated. A comparison between the methods is presented where the change is observed to be substantial with a clear and decisive advantage towards the hybrid method.
