1. 1. Regression Models of 3D Wakes for Propellers

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :Christian Karlsson; [2018]
   Nyckelord :Propeller design; Wake; Velocity distribution; Regression analysis; Fourier series; Skewed-Gaussians; Coherent structure coloring; Propeller design; Medströmsfält; Hastighetsfördelning; Regressionsanalys; Fourierserier; Skeva-Gaussfördelningar; Koherenta struktureringsfärgmetoden;

   Sammanfattning : In this work, regression models for the wake field entering a propeller at certain axial andnominal position have been proposed. Wakes are non-uniform flows following a body immersedin a viscous fluid. We have proposed models for the axial and tangential velocity distribution asfunctions of ship hull and propeller measures.
