Lee, Kurn Chul (2009-05-15)High Mach-number compressible flows with heat release are inherently more complicated than incompressible flows due to, among other reasons, the activation of the thermal energy mode. Such flow fields can experience ...
-
Jain, Sunny (2009-05-15)There has been a continuous effort to unveil the physics of hypersonic flows both experimentally and numerically, in order to achieve an efficient hypersonic vehicle design. With the advent of the high speed computers, a ...

Sharma, Bajrang Lal (2023-03-29)In high speed flows the nature of pressure changes. Pressure evolves from a Lagrange multiplier in low speed flows to a thermodynamic variable at high speeds. The compressible velocity field develops a finite dilatational ...
-
Padgen, Samuel Sebastian (2023-08-09)For the design of hypersonic vehicles the behavior of the boundary layer and accordingly transition is both critical to understand and simultaneously not very well understood. The stability and transition of high-speed ...

Xu, Feng (2017-12-12)The objective of this research is to investigate the interfacial instability of suspensions in a Hele-Shaw cell, which involves a dynamical coupling between particle transport and fluid-fluid interfacial deformations. ...
-
Katariya, Abhilasha Prakash (2009-05-15)In this research, we consider production/inventory management decisions of a rmthat sells its product in two market segments during a nite planning horizon. In thebeginning of each period, the rm makes a decision on how ...

Bhattad, Kapil (Texas A&M University, 2008-10-10)We study the problem of communicating a discrete time analog source over a channel such that the resulting distortion is minimized. For ergodic channels, Shannon showed that separate source and channel coding is optimal. ...
-
Hai, Zhiying (2022-08-25)We present a study on the role of elasticity in causing fingering or fracturing instability during the immiscible displacement process of a viscoelastic fluid by another viscoelastic fluid in a rectilinear Hele-Shaw cell. ...
-
Dutta, Sourav (2017-07-28)We study multiphase, multicomponent flow of incompressible fluids through porous media. Such flows are of vital interest in various applied science and engineering disciplines like geomechanics, groundwater flow and ...
-
Mishra, Varun (2009-06-02)Horizontal wells are drilled to achieve improved reservoir coverage, high production rates, and to overcome water coning problems, etc. Many of these wells often produce at rates much below the expected production rates. ...
-
McMillan, Madeline Nicole (2019-10-22)How laminar flow interacts with distributed roughness has yet to be described in a cohesive fashion. To advance theoretical efforts, a preliminary model inspired by experimental results is proposed here and evaluated. ...
-
Sharma, Abhishek (2015-05-04)Accurate prediction of wave environment is critical to the design of ports, harbors and coastal structures. In this dissertation, two advancements for existing phase-resolving models based on elliptic mild-slope equation ...
-
Monschke, Jason Andrew (2015-09-11)Transient growth is a linear disturbance growth mechanism that plays a key role in roughness-induced boundary-layer transition. It occurs when superposed stable, non-orthogonal continuous spectrum modes experience algebraic ...
-
Alhuwaishel, Fahad (2015-08-06)A concept called “Active Output Filter” (AOF) for performing output filtering in switching converter is proposed. The methodology is based on voltage harmonic injection via a combination of H Bridge and minimized LC filter ...
