Measuring Ultrafast Turbulent Flow Characteristics Using Time-Stretch Imaging

Turbulent flow is a type of gas or liquid flow in which the fluid undergoes irregular fluctuations, or mixing, in which the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction [1]. Some applications in which characteristics of turbulent flow are important include blood flow in arteries, oil transport in pipelines, lava flow, atmosphere and ocean currents, the flow through pumps and turbines, and the flow in boat wakes and around aircraft-wings.
