To investigate the factors affecting complete evaporation of wet steam and describe the influencing mechanism
the liquid droplets were simplified as spherical particles
and the Schiller Naumann model was applied to calculate the force between phases.Combining with the strengthened wall function
the standard k-ε model was employed as the turbulence model to analyze the relationship between complete vaporization length and factors like the heating power
average droplet diameter
steam humidity
wet steam velocity and others.The result shows that
the complete steam vaporization length is inversely proportional to the heating power
while it increases linearly with other three factors.
