Abstract

In this paper, numerical simulations on Y-type drain valve were carried out using Eulerian-Lagrangian model. The simulation results were verified by the experimental ones. It was found that the droplet velocity close to the sealing surface exceeds the threshold values, resulting in serious erosion. To lower down the extent of erosion, a spool featuring labyrinth discs was proposed. The simulation results showed that the maximum droplet velocity and flow capacity of the drain valve with the labyrinth discs are 46% and 78.2% of the values for the valve without the labyrinth discs, respectively. It can be concluded that the usage of labyrinth discs reduces the erosion significantly and is applicable to serious erosion operating conditions.
