Complex approach to research the directional valves

In work the problem of designing the hydroelements with set characteristics and possibility of replacement the experimental operational development by numerical modeling is considered. The analysis is spent for directional valves. It is received that at the sizes of a grid not less than 4 elements on a backlash results of calculations and experiments differ no more, than on 10%. Thus in other area elements have larger size that allows to receive results on the personal computer.
