DataFig12 from Classical hydrodynamics for analogue space–times: open channel flows and thin films. 28 April 2020

Raw data to plot the spatial evolution of the flow and wave speed in addition to their ratio. “Mach number versus space” in a lateral geometric constriction.本数据集为原始数据，可用于绘制流场、波速及其二者比值的空间演化过程，同时涵盖横向几何收缩段内「马赫数（Mach number）随空间变化」的相关数据。
