Abstract:

One presents a mathematical model of the viscous fluid flow with heat transfer around the anemometer hot wire and also in its interior, where is produced of the electrical current distribution caused by the different electric resistances as function of local temperature the conductor wire being supposed at an electric voltage on its ends. For the solving of different equation systems in the two domains, one uses their numerical integration on a polar grid, assuring the solution stability and taking into consideration the specific boundary conditions.
