Instabilities of Flows: With and Without Heat Transfer and Chemical Reaction (CISM International Centre for Mechanical Sciences)

The study of fluid flow instabilities is a cornerstone of modern fluid mechanics, combining theoretical insights with practical applications. Instabilities of Flows: With and Without Heat Transfer and Chemical Reaction offers a comprehensive exploration of this fascinating subject. Written by Tapan Sengupta and Thierry Poinsot, this book provides an in-depth analysis of the mechanisms driving flow instabilities in both classical and emerging contexts, such as those involving thermal gradients and chemical reactions.

Detailed Summary of the Book

The book serves as a unifying resource for understanding flow instabilities in various settings. It first delves into linear and nonlinear theories of instability, setting the stage with fundamental equations and principles. It examines the richness and complexity of flow fields affected by heat transfer processes and the chemical dynamics observed in combustion and reactive systems.

The authors provide critical insights into hydrodynamic instabilities and their manifestations in laminar and turbulent flows. The book then transitions to the impact of thermal gradients on instabilities, highlighting practical examples like internal cooling in gas turbines and atmospheric reentry conditions for space vehicles. Chemical reactions, as a force driving or moderating instabilities, form an equally compelling study. The authors intricately explore combustion dynamics, including flame–flow interactions and instabilities in premixed and non-premixed flames.

Using a blend of theoretical rigor and practical examples, the book equips researchers, engineers, and academicians to address real-world challenges. It also emphasizes numerical techniques as indispensable tools for quantifying and mitigating instabilities.
