Reactive Gas Dynamics

Reactive gas dynamics takes the study of gas dynamics a step further by considering chemical reactions that occur within gases. In many real-world scenarios, gases react with each other, resulting in transformations of their properties, such as temperature, pressure, and composition.

Understanding reactive gas dynamics is crucial in fields such as combustion, chemical engineering, and atmospheric science. It enables scientists to predict how gases will react under various conditions, which has significant implications for both practical applications and theoretical research.

Key Concepts in Reactive Gas Dynamics

Now that we have a general understanding of reactive gas dynamics, let's delve into some key concepts and phenomena associated with this fascinating subject:

Chemical Kinetics

Chemical kinetics is the study of reaction rates, mechanisms, and the factors that influence them. In reactive gas dynamics, understanding chemical kinetics is pivotal in predicting and manipulating the behaviors of gases. Through the study of reaction rates, scientists can determine how fast or slow a reaction occurs, allowing them to control and optimize industrial processes.

Shock Waves

Shock waves are sudden, intense waves that travel through a gas faster than the speed of sound. In reactive gas dynamics, shock waves play a crucial role in the study of supersonic and hypersonic flows. They can dramatically influence combustion processes, propulsion systems, and even astrophysical phenomena.

Detonations and Deflagrations

Detonations and deflagrations refer to the high-speed combustion processes that occur within reactive gases. While detonations involve supersonic combustion waves that propagate at high speeds, deflagrations are subsonic combustion waves. These phenomena are of utmost importance in fields such as propulsion systems, industrial explosions, and detonation engines.

Applications of Reactive Gas Dynamics

Reactive gas dynamics has a wide range of applications across multiple industries. Here are just a few examples:

Combustion Processes

Understanding how reactive gases combust is crucial for applications such as internal combustion engines, gas turbines, and even household heating systems. Reactive gas dynamics studies help engineers optimize combustion processes, making them more efficient and environmentally friendly.

Aerospace Engineering

Reactive gas dynamics plays a vital role in aerospace engineering, enabling the development of efficient jet engines, rockets, and supersonic aircraft. By understanding the behavior of reactive gases, scientists can design aerospace systems that withstand extreme conditions and deliver optimal performance.

Chemical Engineering

Chemical engineers rely on reactive gas dynamics to design and optimize industrial processes involving gases, such as the production of chemicals, pharmaceuticals, and alternative energy sources. By manipulating the reactions and behaviors of gases, they can increase efficiency and reduce waste.

Atmospheric Science

Reactive gas dynamics helps scientists understand the complex interactions between gases in Earth's atmosphere. This knowledge is crucial for studying climate change, air pollution, and atmospheric phenomena such as thunderstorms and tornadoes.

Reactive gas dynamics is a captivating field that explores the intricate dynamics of gases under various conditions. By understanding the behaviors of reactive gases, scientists can make groundbreaking advancements in fields ranging from aerospace engineering to atmospheric science. As you venture into the depths of reactive gas dynamics, remember that this is just the tip of the iceberg. Countless discoveries and breakthroughs await as we continue to unravel the secrets of our vast universe.

In high energy gas flows, at high velocities and high temperatures, physical and chemical processes such as molecular vibrational excitation, dissociation, ionisation or various reactions take place and deeply influence the structure of the flows. The characteristic times of these processes have the same order of magnitude as aerodynamic characteristic times, so that these reactive media are generally in thermodynamic and chemical non-equilibrium. This book presents
a general introductory study of these media. In the first part their fundamental statistical aspects are described, starting from their discrete structure and taking into account the interactions between elementary particles: transport phenomena, relaxation and kinetics as well as their coupling are
analysed and illustrated by many examples. The second part deals with the macroscopic re-entry bodies. Finally, the experimental aspects of these flows, their simulations in shock tubes and shock tunnels are described, as well as their application, particularly in the aerospatial domain.

This book is intended for students that have acquired a basic knowledge in thermodynamics, statistical physics and fluid mechanics. It will also be of interest to engineers in research and industry, in particular in the aerospace industry, and more generally to all researchers trying to simulate and calculate complex reactive flows.
