  1. 1. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

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

    Author : Eglantin Gjoni; [2023]
    Keywords : ;

    Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE

    Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

  5. 4. Ride Quality and Drivability of a Typical Passenger Car subject to Engine/Driveline and Road Non-uniformities Excitations

    University essay from Fordonssystem

    Author : Neda Nickmehr; [2011]
    Keywords : Ride quality; Driveline; Engine excitations; Road non-uniformities; Suspension System; Torsional vibration; Random process;

    Abstract : The aim of this work is to evaluate ride quality of a typical passenger car. This requires both identifying the excitation resources, which result to undesired noise inside the vehicle, and studying human reaction t applied vibration. READ MORE
