| Abstract: | To understand the properties of the transfer function of parallel tube-manifold system in wind tunnel test,an analysis is made of several parameters related to the transfer function on the basis of the dissipative model with some qualitative rules on perallel tube-manifold system obtained. It's pointed out that the length and interior diameter of PVC tube, the dimension and position of restrictor are the major factors that affect the transfer function in the usual range of dimensions, which provides a basis for the design of the parallel tube-manifold system. |
