Hosseinpour-Zoonozi, Nima (Texas A&M University, 2007-04-25)The proposed work provides a new definition of the pressure derivative function [that is the ò-derivative function, ÃÂp òd(t)], which is defined as the derivative of the logarithm of pressure drop data with respect ...
-
Sharma, Gaurav (Texas A&M University, 2004-09-30)Particle-laden turbulent flow through a straight square duct at Reτ = 300 is studied using direct numerical simulation (DNS) and Lagrangian particle tracking. A parallelized 3-D particle tracking direct numerical simulation ...
-
Al Dini, Salem A. S. (Texas A&M University, 2007-04-25)Electrohydrodynamic (EHD) pumping of single and two-phase media is attractive for terrestrial and outer space applications since it is non-mechanical, lightweight, and involves no moving parts. In addition to pure pumping ...
-
Park, Seungkyung (2009-05-15)Recent advances in microfluidic technologies have enabled integration of the functional units for biological and chemical analysis onto miniaturized chips, called Labon- a-Chip (LOC). However, the effective manipulation ...
-
Bahukudumbi, Pradipkumar (Texas A&M University, 2007-09-17)Chemically and physically patterned surfaces can be used as templates to guide nano- and micro- scale particle assembly, but the design is often limited by an inability to sufficiently characterize how pattern features ...
-
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 ...
-
Kim, Bo Hung (2009-06-02)A graphical preprocessor for Spectral Element Method (SEM) is developed with an emphasis on user friendly graphical interface and instructive element construction. The interface of the preprocessor helps users with every ...
