    Flow simulation in Valves

      I want to analyse the flow through a valve. To do this, how much length of a pipe should be taken across the valve to apply the boundary conditions? Is there any thumb rule for this?

          I guess it all depends. As a rule of thumb, you should model any geometry that you believe will affect the flow.
          If there is no significant geometry changes before the valve inlet, you can specify a fully developed flow at the inlet.

          Usually where it makes the most difference is the valve OUTLET. Make sure you add enough geometry after the valve to account for this.
