Abstract:
Flapper-nozzle type valve is commonly used for precision, flow control in pneumatic systems. For the purpose of analysis and design the paper is concerned with nonlinear mass flow rate of the valve taking into account different flow regimes. Flow rate is static, nonlinear function and could not be solved in analytical form. In this paper Particle Swarm Optimization method is used for numerical solution. Depending on supply pressure and flow area ratio along the static characteristic different segment can be observed.

Key words:
flapper-nozzle valve,mass flow rate characteristic,PSO optimization method
