The theoretical equations which govern the one-dimensional flows of a gas particle mixture in a nozzle have been extended to the case where a continuous distribution of particle size is present. Using them a few numerical experiments have been performed for mist flows composed of air and water-particles, which are commonly applied to the secondary cooling zone in the continuous casting. The case has been treated where the radius of water-particle ranges between 1 and 50μm. Again, the nozzle with a parallel region in which the sectinal area is constant has been introduced to the numerical calculation. The results so obtained have been discussed from a numerical point of view. Furthermore, it has been pointed out that the flow properties strongly depend upon the particle-to-gas mass flow rate ratio, the reservoir pressure and the nozzle geometry.
