SIMPLE aerodynamic configurations under even modest conditions can exhibit complex
flows with a wide range of temporal and spatial features. It has become common practice in …

Closed-loop turbulence control is a critical enabler of aerodynamic drag reduction, lift
increase, mixing enhancement, and noise reduction. Current and future applications have …

高超声速飞行器边界层容易经历层流/湍流转捩, 层流流动和湍流流动在摩擦阻力, 热交换,
噪声和掺混等方面有巨大差别, 转捩问题已成为制约高超声速技术突破的基础科学问题之一 …

THE field of fluid mechanics involves a range of rich and vibrant problems with complex
dynamics stemming from instabilities, nonlinearities, and turbulence. The analysis of these …

This book is an introduction to machine learning control (MLC), a surprisingly simple model-
free methodology to tame complex nonlinear systems. These systems are assumed to be …

In this work, we review the physics of the liquid ejection by the application of electric fields,
paying special attention to the steady cone-jet mode of electrospray. We aim to provide a …

Supersonic jets, particularly shock-containing jets, often exhibit high-intensity, discrete-
frequency acoustic tones. These tones are the signature of an aeroacoustic resonance loop …

This work studies the application of a reinforcement learning (RL)-based flow control
strategy to the flow past a cylinder confined between two walls to suppress vortex shedding …

Dripping, jetting and tip streaming have been studied up to a certain point separately by both
fluid mechanics and microfluidics communities, the former focusing on fundamental aspects …

The precessing vortex core (PVC) is a coherent flow structure that is often encountered in
swirling flows in gas turbine (GT) combustors. In some swirl combustors, it has been …
