Abstract
The article proposes a method for determining the throughput capacity of shut-off valves of various types (ball valve, straight-through and direct-flow valves) by numerical simulation based on computational fluid dynamics. A comparative analysis of the throughput capacity values of ball, straight-through and direct-flow valves calculated by this method was performed. The results of calculation and experiment are compared. The disadvantages and advantages of shut-off valves are indicated, recommendations for their use are given. It was established that when the shutter is fully opened, the absolute discrepancy between the calculated and experimental data is 0 ... 27 %. The analysis of the obtained results confirmed the possibility of using the proposed method for calculating the throughput capacity of shut-off valves of the specified type.
