As demand for more efficient and higher-performing aerospace platforms increases there is a need to address challenges that have been left unsolved through a more comprehensive understanding of the complex flowfields and the underlying...
The air intake captures the freestream airflow and delivers it to the engine of the parent vehicle for thrust production. The shockwave boundary layer interactions (SBLI) in the intake duct play an important role in defining the flow...
Liquid helium-4 undergoes a phase transition below about 2.17 K where it is called the superfluid (He II). He II is a non-classical fluid which is one of the very few macroscopic manifestation of the quantum mechanics. He II entails...
Unsteady fluid flows have complex dynamics due to the nonlinear interactions amongst vortical elements. In this thesis, a network-theoretic framework is developed to describe vortical and modal (coherent structure) interactions in...
This study aims to examine the use of a fundamental thermal input for separation control and provide a design guideline via resolvent analysis. The use of the thermal actuator is motivated by the interest in the use of thermal-energy...
Propagation of laser beams through complex flow field caused by radar system housing has been an important topic for many years dating back to the mid 1960s. Applications for radar systems range from missile defense, directed energy to...
The objective of this computational study is to examine and quantify the influence of fundamental flow control inputs in suppressing flow separation over a canonical airfoil. Most flow control studies to this date have relied on the...
Systems with a priori unknown, and time-varying dynamic behavior pose a significant challenge in the field of Nonlinear Model Predictive Control (NMPC). When both the identification of the nonlinear system and the optimization of control...
The present numerical investigation aims to uncover the inherent instability in compressible cavity flows and aid designs of effective flow control to alter undesirable flow features. Two-dimensional (2D) and three-dimensional (3D)...
Active flow control can achieve substantial performance gains and meet the challenges of next-generation air vehicles and energy harvesting devices. The use of active flow control techniques with the deflecting flap or morphing surfaces...
