Fundamental Studies of Shock-Driven Hydrodynamic Instabilities

This book explores the latest progress on the hydrodynamic instabilities induced by a shock wave, particularly RM (Richtmyer–Meshkov) instability, and introduces new experimental methods to generate shape-controllable two-dimensional gaseous interfaces, thickness-controllable gas layers, and water droplets embedded with a vapour bubble in shock-tube experiments. It also establishes a universal nonlinear theory to predict the RM instability of a shocked multi-mode interface and quantifies the effects of interface-coupling and reverberating waves on the hydrodynamic instabilities of a shocked multi-layer interface.

This comprehensive book delves into the latest advancements in the study of hydrodynamic instabilities induced by shock waves, with a specific focus on the RM (Richtmyer–Meshkov) instability. Hydrodynamic instabilities hold significant importance in diverse industrial and scientific domains, including inertial confinement fusion, supersonic combustion, and supernova explosions. This book employs both experimental and theoretical approaches to explore the shock-driven instabilities of complex gas-gas and gas-liquid interfaces. The primary challenge in conducting experimental investigations of RM instability, particularly in shock-tube scenarios, lies in creating an idealized initial interface due to the extreme sensitivity of the instability to the initial condition. To overcome this obstacle, this book introduces innovative experimental methods to generate shape-controllable two-dimensional gaseous interfaces, thickness-controllable gas layers, and water droplets embedded with a vapor bubble in shock-tube experiments. It comprehensively covers the latest experiments and theories on the shock-driven hydrodynamic instabilities of multi-mode, multi-layer, and multi-phase interfaces. The book explores the influence of mode-competition, interface-coupling, and phase-transition on interface evolution, respectively. Furthermore, this book establishes a universal nonlinear theory to predict the RM instability of a shocked multi-mode interface through spectrum analysis. It quantifies the effects of interface-coupling and reverberating waves on the hydrodynamic instabilities of a shocked multi-layer interface. Additionally, this book presents experimental studies of the interaction between a shock wave and a multi-phase droplet and proposes a modified Rayleigh-Plesset equation to predict the collapse of a vapor bubble inside a droplet.
