FREEZING HEAT TRANSFER BETWEEN TWO COOLED PARALLEL PLATES WITH SEPARATED REGION
Аннотация
Freezing of turbulent water flow between two horizontal cooled parallel plates with the separated region has been investigated experimentally. The flow separation was induced by vertical plates (two-dimensional orifice) situated at the inlet of the parallel plates. The degree of flow separation was varied by employing vertical thin plates of various heights. Three kinds of the vertical plates with 8.0, 9.8, and 12.5 mm in height were utilized. The Reynolds number and the cooling temperature ratio, respectively, ranged from 3.45 × 103 to 1.73 × 104 and from 7.0 to 20.0. The measurements show that the flow separation exerts a marked influence on the local ice formation characteristics. The location of the first ice layer step and the average heat transfer at the ice surface were found to be correlated as a function of the Reynolds number, the cooling temperature ratio, and the orifice height ratio.
