forced convection
Hi!I have to calculate the heat transfer coefficient between a moving fluid and a wall.Until now I obtained very high results far from I expected (for water moving in a tube 15 millimeters wide I obtained a convection coefficient of about 10^6 W/m^2K, water velocity was about 5 m/s).Can you give me some advice to set this calculation?How I can check mesh near the wall to obtain correct results? Thank'you to all! Bye
