| Title of the article | Motion of a viscous liquid in the pores of the coarse granular coalescing nozzle with a nonlinear resistance law |
| Abstract. | In this article, we set and solved problems of determining the motion of a viscous liquid in the pores of the coarse granular coalescing nozzle with a linear resistance law. During the liquid filtration in the pores of the loading, liquid particles move with speed and acceleration changing in magnitude and direction. Because of the motion complexity, the velocities of the individual particles cannot be considered. Therefore, similar to the filtration theory, flow rates through a certain area are considered, and not velocities. The volume depends on the arrangement of the loading granules in a cylinder. The joint analysis of the calculated and experimental results showed satisfactory agreement of the hydraulic gradient values in a coarse loading about 4,0 mm fraction at a temperature of 20 0С, 30 0С, 40 0С, 50 0С and velocity from 50,9 to 97,4 m/s; and 17,5 mm fraction at a temperature of 20 0С, 30 0С, 40 0С, 50 0С and velocity from 60,0 to 115,7 m/s. |
