This book examines what we know about the physics underlying the onset of instability in liquid sheets and jets.The theme of this book is an exposition of what we know about the physicsunderlying the onset of instability in liquid sheets and jets. Wave motionand breakup phenomena subsequent to the onset of instability are alsocarefully explained. Physical concepts are established through rigorousmathematics, accurate numerical analyses and comparison of theory withexperiment. Exercises are provided for students new to the subject; and, researchersinterested in transition to turbulence, hydrodynamic stability or combustionwill find this book a highly useful resource, whether their background liesin engineering, physics, chemistry, biology, medicine or appliedmathematics.The theme of this book is an exposition of what we know about the physicsunderlying the onset of instability in liquid sheets and jets.
