1. 1. Development of a Free Surface Capability in a RANS Solver with Coupled Equations and Overset Grids

   Författare :Michal Orych; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-surface; overset; RANS;

   Sammanfattning : This thesis is a result of investigations carried out during the implementation of a free surface capturing method in a RANS solver. The work consists of two distinct parts which complement each other, and the purpose is to improve the free surface interface sharpness and to reduce numerical diffusion of the gravity waves.
