Abstract
A transient laminar flow in a spool valve has been studied via numerical analysis. First, steady laminar flow fields were investigated for several values of pressure difference between upstream and downstream boundaries. For a pressure difference larger than a critical value; two solutions with distinct jet angles were obtained. Then the time-dependent numerical analysis was performed. The results for a step change of pressure difference revealed that the Step response of the flow is modeled with two time constants which are essentially the same as discussed in the previous pipe orifice analysis.
