Throat Section

A theoretical axisymmetric model of flow through conical Venturimeters, capable of solution by digital computer, has been developed to predict the development of the turbulent boundary layer along the convergent and throat section where the flow is subjected to a favorable pressure gradient. A computation method was developed to solve the momentum, auxiliary, continuity, and state equations simultaneously step-by-step. For a given inlet condition the throat condition can be predicted. Theoretical predictions were compared with experimental results obtained from two 10-in-dia Venturimeters of area ratios 0.25 and 0.5. The agreement between the theory and detailed boundary-layer surveys is good.
