L.H.C. Cunha; G. R. Anjos; N. Mangiavacchi

Uberlândia, Brazil

Keywords: Conjugated Heat Transfer, Stream Function-Vorticity, Semi-Lagrangian Method

Conjugated heat transfer problems are the ones where it is necessary to understand how heat convection in a fluid influences the temperature in solid regions. Instead of solving the Navier-Stokes equation with its...

Stream Function-Vorticity Formulation and Heat Transport Using FEM for Unstructured Meshes and Complex Domains

L.H.C. Cunha; G. R. Anjos; N. Mangiavacchi

Rio de Janeiro, Brazil

Keywords: Finite Element Method, heat transport, Streamfunction

The stream function-vorticity formulation is a useful alternative to solving the Navier-Stokes equations in two dimensional domain. One of its major difficulties is the lack of boundary conditions for vorticity, and...
