1. 1. Linear stability Analysis of Viscoelastic Flows

   Master-uppsats, KTH/Mekanik

   Författare :Mengqi Zhang; [2012]
   Nyckelord :;

   Sammanfattning : The goal of present work is to investigate the instability of jet ow, mixing layer and Poiseuille ow of viscoelastic uids. According to Boeta et al: [4], small elastic eect in Kolmogorov ow will result in increasing critical Re for hydrodynamic instability, however, at high elasticity a new instability of elastic nature occurs even at vanishing Re.

3. 2. Luftens strömning i och över en skog – Utvärdering av en ’mixing-layer’ hypotes

   Magister-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Johan Arnqvist; [2009]
   Nyckelord :Mixing-layer; Canopy; Wind profile; Kelvin-Helmholtz waves; Roughness sublayer; Nyckelord: Mixing-layer; Canopy; Vindprofil; Skog; Kelvin-Helmoltz-vågor; Roughness sublayer;

   Sammanfattning : A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. LÄS MER
