  1. 1. Numerical Investigation of Flow Induced Noise in a Simplified HVAC Duct with OpenFOAM

    University essay from KTH/Flygdynamik

    Author : Cong Wang; [2013]
    Keywords : ;

    Abstract : Due to the growing demand for comfort, the noise generated by HVAC components should be considered by the designers. Flow induced noise is one of the major contributors to the noise in HVAC systems. By means of computational aero-acoustics(CAA), the mechanism of noise generationis able to be studiedin the design phase. READ MORE

  2. 2. A Wave Propagation Solver for Computational Aero-Acoustics

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Elin Solberg; [2012-03-14]
    Keywords : Helmholtz equation; Lighthill’s analogy; computationalaero-acoustics; finite element method; Galerkin least-squares stabilization; infinite element method; computational fluid dynamics;

    Abstract : Simulation software is increasingly replacing traditional physicaltesting in the process of product development, as it can in many casesreduce development times and costs. In a variety of applications, thereduction of noise is an important aspect of the product design andusing methods from the field of computational aero-acoustics (CAA),the generation and propagation of sound in air may be simulated.

  5. 5. Processing of the Cluster EFW Internal Burst Data

    University essay from Luleå/Department of Computer Science, Electrical and Space Engineering

    Author : Johan Reponen; [2011]
    Keywords : Cluster; Space; Physics;

    Abstract : The internal burst data from the EFW instrument on the Cluster mission have great potential but needs some processing before becoming a part of the Cluster Active Archive (CAA) where all other viable scientific data from the mission is represented. The aim of this thesis is to create a program that that can correct large quantities of the internal burst data, plot the data comparing it to the normal mode data, and save the results. READ MORE
