GEOMETRICAL CHARACTERISTICS OF THE LAYER OF THE IRREGULAR NOZZLE FROM SHORT SPRING ELEMENTS
Abstract
The article presents results of analytical and experimental studies of the geometric characteristics of the nozzle layer of the short spring members formed of wire 0,4 mm in diameter with an aspect ratio l / d = 1,45 and 2,0. These elements have an equivalent diameter of 6.6 mm and 5,2 mm respectively, and the shape factor reaches values of 0,45 and 0,40.It is found that the value of the specific interfacial surface layers of such elements in 1,1-1,3 times higher than the most effective parameter for nozzle (10×10×0,5 Raschig rings) with porosity layers remains roughly the same and in the range 0,854-0,880. For the first time introduced and defined coefficient of unevenness of the packing layer and compression section of the living. For the layer of the investigated element is defined as the equivalent diameter of the channel in the layer.
