Tichenor, Nathan R. (2010-10-12)High-speed high Reynolds number boundary layer flows with mechanical non-equilibrium effects have numerous practical applications; examples include access-to-space ascent, re-entry and descent, and military hypersonic ...
-
Johnson, Shalom (2011-08-08)In todays highly maneuverable jet aircraft designs, aircraft are required to have a propulsion system that can operate during sudden accelerations and rapid changes in angle-of-attack. Consequently, the compressor of the ...
-
Semper, Michael Thomas (2013-05-15)The purpose of the current study was to answer several questions related to hypersonic, low Reynolds number, turbulent boundary layers, of which available data related to turbulence quantities is scarce. To that end, a ...

Fuller, T. J. (2010-10-12)The technical feasibility of hypersonic flight (i.e., re-entry, hypersonic flight vehicles, cruise missiles, etc.) hinges on our ability to understand, predict, and control the transport of turbulence in the presence of ...
-
Sahoo, Dipankar (Texas A&M University, 2008-10-10)Improved basic understanding, predictability, and controllability of vortex-dominated and unsteady aerodynamic flows are important in enhancement of the performance of next generation helicopters. The primary objective of ...
-
Zhu, Xuehua (Texas A&M University, 2004-11-15)Gas bearings enable successful applications in high speed oil-free microturbomachinery. This thesis presents analysis and experiments of the dynamic performance of a rotor supported on Rayleigh step gas bearings. Comprehensive ...
-
Kim, Kihwan (Texas A&M University, 2006-04-12)The primary goal of this research is to assess the effect of synthetic jets on flow separation and provide a feedback control strategy for flow separation using synthetic jets. The feedback control synthesis is conducted ...
-
Kumar, Abhinav (2009-05-15)Computational investigations were carried out on an advanced serpentine jet engine inlet duct to understand the development and propagation of secondary flow structures. Computational analysis which went in tandem with ...
-
Miller, Adam Cole (Texas A&M University, 2005-02-17)An experimental investigation was undertaken to determine the ability of Synthetic Jet Actuators to control the aerodynamic properties of a wing. The Synthetic Jet Actuator (SJA) was placed at two separate positions on ...

Holtzapple, Mark T.; Rediniotis, Othon (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2010-08-24)According to one embodiment of the invention, a system for altering fluid flow includes a main body having a first fluid flowing therethrough, a plurality of conduits disposed within the main body to form a plurality of ...
-
Chambers, Steven B. (Texas A&M University, 2005-02-17)Computational Fluid Dynamics (CFD) is a field that is constantly advancing. Its advances in terms of capabilities are a result of new theories, faster computers, and new numerical methods. In this thesis, advances in the ...
-
Surendran, Arun (2009-08-24)Even simple observation of stock price graphs can reveal dominant patterns. In our work, we will refer to such re-occurring, dominant patterns as “coherent structures”, a term borrowed from the theory of turbulence in fluid ...
-
Joly, Michael Marie (2014-07-02)Research on high-speed air-breathing propulsion aims at developing aircraft with antipodal range and space access. Before reaching high speed at high altitude, the flight vehicle needs to accelerate from takeoff to scramjet ...
-
Loizou, Loizos (2012-02-14)Trough waveguides (TWG) have been utilized in a variety of radio frequency (RF) and other related applications including radar, the treatment of hypothermia and in the generation of plasmas. Perturbing the guided wave in ...
