Verification Dynamic Response for Sinusoidal Wave Flow in Narrow Rectangular Channel

Abstract

In this study, we experimentally studied the dynamic response of the sinusoidal single-phase flow in a horizontal narrow rectangular pipe. The experimental results show that, in narrow rectangular channel, the flowrate and the pressure drop also meet the first order dynamic response system phenomenon. The statistic results of prediction by dynamic response system theory shows that, for smaller frequency flow condition, the predictions are precisely, while for higher frequency, the prediction errors are relative bigger, which indicates a research point, high frequency sinusoidal flow, to put effort on.
