Yang, Pengze (2019-03-18)The improvement in brake thermal efficiency of Gasoline Direct Injection (GDI) engines is accompanied by a significant increase in Particulate Matter (PM) and Particulate Number (PN) emissions as compared to (multi)Port ...
-
Yang, Pengze (2015-12-11)Cavitation generally occurs when the pressure at certain location drops to the vapor pressure and the liquid water evaporates as a consequence. For the past several decades, numerous experimental researches have been ...

Li, Qiang (2009-05-15)Motivated by the demand of increasing data rate in wireless communication, multiple-antenna communication is becoming a key technology in the next generation wireless system. This dissertation considers three different ...
-
Kamble, Chetna (2021-04-27)Challenges in turbulence modeling are often associated with a trade-off between accuracy of flow physics and computational effort. For complex industry-relevant flows, high computational costs require engineers to adopt ...
-
Schwaenen, Markus (2012-07-16)Gas turbine engines are the main propulsion source for world wide aviation and are also used for power generation. Even though they rely mainly on fossil fuel and emit climate active gasses, their importance is not likely ...

PANS method of turbulence: simulation of high and low Reynolds number flows past a circular cylinder Lakshmipathy, Sunil (Texas A&M University, 2006-04-12)The objective of the study is to investigate the capability of PANS (Partially Averaged Navier-Stokes Simulation) model over a wide range of Reynolds numbers and flow physics. In this regard, numerical simulations of ...

Reyes, Dasia Ann (2009-05-15)Partially Averaged Navier-Stokes (PANS) turbulence method provides a closuremodel for any degree of velocity field altering - ranging from completely resolved Di-rect Numerical Simulation (DNS) to completely averaged ...
-
Lakshmipathy, Sunil (2010-07-14)The work presented in this dissertation concerns continued development, validation and verification of the partially averaged Navier-Stokes (PANS) method - a variable resolution closure model for turbulence. Linear eddy ...
-
Bertsch, Rebecca Lynne (2011-10-21)Rapid distortion theory (RDT) is applied to compressible ideal-gas turbulence subjected to homogeneous shear flow. The study examines the linear or rapid processes present in turbulence evolution. Specific areas of ...
-
Hsu, Teh-Hsuan (2009-05-15)In this thesis, we design a robust concatenated code for the Multiple-Input Multiple-Output (MIMO) system in the presence of slow Rayleigh fading with no channel side information at the transmitter (no CSIT) and perfect ...
-
Denissen, Nicholas Allen (2012-07-16)This dissertation analyzes the effect of periodic roughness elements on the stability of a flat plate boundary layer. Receptivity data is extracted from direct numerical simulations and experimental data and the results ...
-
Guo, Xiaoyu (2019-04-09)In this research, we study a macroscopic traffic model, Payne-Whitham (PW) model, with an anticipation source term. The anticipation source describes how the traffic adjusts its speed based on the condition ahead. With the ...
-
Kaul, Sandeep P (2014-08-19)Reservoir simulation studies are the most detailed analysis that can be performed in order to evaluate future performance and remaining reserves of a reservoir, given the in-place volumes. This holds true both for conventional ...
-
Tian, Jing (2016-05-18)Chaos and turbulence are two important topics in nonlinear dynamics. In this study, two problems related to chaos and turbulence modelling are presented. They are the chaotic vibration phenomenon in high-dimensional partial ...
