Natural convection flows in complex cavities by BEMŠkerget, Leopold (Avtor) Hriberšek, Matjaž (Avtor) Žunič, Zoran (Avtor) fluid dynamicsnatural convectionboundary element methoddifferential equationsclosed cavityA numerical method for the solution of Navier-Stokes equations is developed using an integral representation of the conservation equations. The velocity- vorticity formulation is employed, where the kinematics is given with the Poisson equation for a velocity vector, while the kinetics is represented with the vorticity transport equation. The corresponding boundary-domain integral equations are presented along with discussions of the kinetics and kinematics of the fluid flow problem. THE BEM formulation is developed and tested for natural convection flows in closed cavities with complex geometries.20032012-06-01 12:03:25Neznano27694sl
