Title Flat convection currents at the surface of open high-temperature baths for industrial treatment

Abstract Aerodynamic measurements taken on the basis of formulae proposed in the literature, to determine the air velocity distribution in convection currents formed on the surface of baths at temperatures well above that of the ambient air, are described in an attempt to obtain data for ventilation design. The results confirmed the practical value of the formulae used and demonstrated the need to extract a greater volume of air from the centre than from the edges of the bath. The air volume extracted should be proportional to the distribution of air velocities in the convection current. Local exhaust systems should thus provide for air flow regulation the whole length of the baths.
