Abstract
A test rig to be used for time-dependent static pressure and velocity distribution measurements in a pulsatile pipe flow with laminar, transitional and turbulent regimes was initially designed and constructed. An interactive data acquisition and control system including data storage acquisition, and processing of the measured data together with interactive control of corresponding test rig components was designed and operated on the constructed test rig. A high speed computer aided processing of time-dependent pulsatile flow measurements was thus achieved sensitively by means of this interactive system. The systematic experiments on velocity and frictional loss of pulsatile pipe flow could be carried out easily on the test rig in a short time period. The operation principles and advantages of the system are discussed here in sufficient detail.
