HRYB, D. E.  e  GOLDSCHMIT, M. B.. Thermal interaction model between a fluid flow and a solid. Lat. Am. appl. res. [online]. 2009, vol.39, n.2, pp.119-125. ISSN 0327-0793.

A thermal interaction model between a turbulent fluid flow and a solid was developed. The heat exchange is modeled by means of a Newton cooling law where the convective heat transfer coefficient is calculated using thermal wall laws. The finite element method was employed to solve the conservation equations. The model gives the possibility that the fluid and solid meshes are not connected; this generates a great flexibility in meshing and in geometry modification. The domains coupling algorithm was verified using simple problems. Finally, the model developed was validated and applied successfully to the simulation of the fluid dynamic thermal behavior of hot dip galvanizing bath.
