The continual study of shock wave boundary layer interactions (SBLIs) is driven by their presence on the internal and external surfaces of transonic, supersonic, and hypersonic flight vehicles. SBLIs manifest in a myriad of practical...
This work presents two alternatives to optimize the performance of Rankine cycles. The first approach is focused on the spatial distribution of the areas used in the heat exchange process, and the second approach is intended to study the...
This work describes a tool for configuring and analyzing the weight of combined cycle power plant, designed for shipboard applications. The effects that varying selected combined cycle parameters have on the weight and the efficiency are...
Shockwave boundary layer interactions (SBLI) occur on both internal and external surfaces and adversely affect both the structural and propulsive performance of high-speed flight vehicles operating in the trans/super/hypersonic flow...
Asymmetric jets are becoming more prevalent and may offer significant advantages over traditional axisymmetric nozzles for propulsion as well as fluidic mixing applications. The purpose of this work is two fold: 1) to investigate the...
It is desirable to use nanostructured composites to produce high-strength, high-conductive materials for magnet development. In this research, severe plastic deformation (e ≥ 2.0) is used to produce nanostructured Cu-Ag composites in an...
Wingtip vortices develop at the tips of aircraft wings due to a pressure imbalance during the process of generating lift. These vortices significantly increase the total aerodynamic drag of an aircraft at high-lift flight conditions such...
This thesis describes the development of a new piezohydraulic actuator for integration into a microjet flow control system. The piezohydraulic actuator utilizes a lead zirconate titanate (PZT) stack actuator and a hydraulic amplification...
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...
The leading edge slat of a high-lift system is known to be a large contributor to the overall radiated acoustic field from an aircraft during the approach phase of the flight path. This is due to the unsteady flow field generated in the...
Solar stills are a popular choice for distilling water and removing harmful contaminants like arsenic and other minerals in some rural parts of Argentina. The processes involved in solar still are environment friendly as they are driven...
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...
Control of Dynamic Stall using microjet perturbation at the upper, leading edge was studied experimentally in a subsonic wind tunnel facility. A NACA 0015 airfoil was fabricated with a field of microjets (200- or 400-micrometers in...
Several animals build structures to shield themselves from external threats. In some species, however, the function of these constructions goes way beyond that of a simple physical barrier. The odd-shaped mounds created by soil termites...
Intense noise levels produced by high-speed military aircraft have adverse impact on the personnel and surrounding structures. Noise levels are often above 120dB (the human hearing pain threshold), which leads to physical and mental...
