Schematic description of dendritic solidification into a continuously cooled liquid. The heat flux, , released at the solid-liquid interface, is removed through the liquid by externally forced cooling that is laterally uniform. The temperature gradient ahead of the solidifying front is negative and the solid fraction is constant far away from the dendrite tip region.
Theoretically calculated ice fraction (theory) of spongy ice formed by impinging water droplets at different values of the estimated droplet Stefan number . Data of calorimetrically measured ice fraction (experiments) are from icing wind tunnel icing experiments (Ref. 11), in which droplet temperature was estimated based on the air temperature as , and are based on three measurements around the nominal .
Solid fraction estimated by Eq. (15) based on photographs of directional solidification experiments of succinonitrile (SCN). The mean of these data for the solid fraction is .
