Book Description
This book provides a comprehensive treatment of passive and active flow control in fluid dynamics, with an emphasis on utilizing fluid instabilities for enhancing control performance. Examples are given from a wide range of technologically important flow fields occurring in aerospace applications, from low-subsonic to hypersonic Mach numbers. This essential book can be used for both research and teaching on the topics of fluid instabilities, fluid measurement and flow actuator techniques, and problem sets are provided at the end of each chapter to reinforce key concepts and further extend readers' understanding of the field. The solutions manual is available as a online resource for instructors. The text is well suited for both graduate students in fluid dynamics and for practising engineers in the aerodynamics design field.

Book Description
This work focused on instability, routes to chaos, and transition to turbulence in an axisymmetric jet. The research focused on three basic tasks. The first involved the search for evidence of low dimensional strange attractors in a naturally excited condition. The theoretical analog was the construction of low-dimensional model equations for this flow. The second involved 3-D (non-axisymmetric) periodic forcing of the jet to lead to the enhanced growth of 3-D modes. This was to focus on natural resonant mechanisms involving natural instability modes of the shear layer and jet core. The theoretical analysis for this part was to predict the conditions for the most resonant interactions, which would maximize our ability to control the jet outcome. The third task was to integrate the previous tasks to exploit important mode interactions which lead to strong nonlinear regimes and or random or chaotic states. In this phase, we accomplished this through intrinsic forcing of the jet by 'enhanced feedback'. The results of the work have covered all these tasks, and yielded many new fundamental results basic to dynamical systems with feedback.

Book Description
The stability characteristics of a laminar, axisymmetric jet, issuing from fully developed Poiseuille flow, are investigated. The jet preferred frequency, as inferred from surveys of u'-spectra, is found to yield a Strouhal number (St) that depends on the Reynolds number (R); St and R are based on the jet diameter (D) and the average velocity (U sub av) at the jet origin. The value of St increases with increasing R in the range 400 less than approximately R less than approximately 4000, attaining an asymptotic value of about 0.45. Flow visualization confirms that the instability is primarily in a helical mode, as predicted by stability analyses. Analyses do predict a similar St versus R variation in approximately the correct St-range. However, the R-range where this is predicted is lower than that found experimentally. Zaman, K. B. M.
