Asymmetrical Flow Simulation of Icing Effects in SDuct Inlets at Angle of Attack
(De Gruyter, 2011) 
Passive Control of Supersonic Rectangular Jets through Boundary Layer Swirl
(De Gruyter, 2013)Mixing characteristics of underexpanded supersonic jets emerging from plane and notched rectangular nozzles are computationally studied using nozzle exit boundary layer swirl as a mean of passive flow control. The coupling ... 
Catalyzed diesel particulate filter modeling
(De Gruyter, 201302)An increasing environmental concern for diesel particulate emissions has led to the development of efficient and robust diesel particulate filters (DPF). Although the main function of a DPF is to filter solid particles, ... 
Effects of Fiber Volume on Modal Response of ThroughThickness Angle Interlock Textile Composites
(Scientific Research Publishing, 201401)Prior static studies of threedimensionally woven carbon/epoxy textile composites show that large interlaminar normal and shear strains occur as a result of layer waviness under static compression loading. This study ... 
Reynolds number effects on flow/acoustic mechanisms in spherical windscreens
(Acoustical Society of America, 2003)There is a practical need to fully understand the mechanisms involved in the flow/pressure fluctuations around a screened microphone. A stream of uniform flow with lowfrequency turbulence encountering a rigid, impermeable ... 
Nonlinear spacing and frequency effects of an oscillating cylinder in the wake of a stationary cylinder
(American Institute of Physics, 2010)Nonlinear responses to a transversely oscillating cylinder in the wake of a stationary upstream cylinder are studied theoretically by using an immersedboundary method at Re=100. Response states are investigated in the ... 
A computational study of the effect of windscreen shape and flow resistivity on turbulent wind noise reduction
(Acoustical Society of America, 2011)In this paper, numerical simulations are used to study the turbulentwind noise reduction effect of microphone windscreens with varying shapes and flow resistivities. Typical windscreen shapes consisting of circular, ... 
A HighOrder Unifying Discontinuous Formulation for the NavierStokes Equations on 3D Mixed Grids
(EDP Sciences, 20110516)The newly developed unifying discontinuous formulation named the correction procedure via reconstruction (CPR) for conservation laws is extended to solve the NavierStokes equations for 3D mixed grids. In the current ... 
A Computational Investigation of Icing effects on an SDuct Inlet
(Freund Publishing House, 201012)The effects of a typical glaze ice accretion shape on the performance of the M2129 Sduct inlet are computationally investigated for a range of flight Mach numbers. A ReynoldsAveraged NavierStokes (RANS) code with ko> ... 
Altimeter sampling characteristics using a single satellite
(Wiley, 19980515)Altimetric satellites have characteristic sampling patterns in both space and time based on their repeat period and orbit inclination. Aliased phenomena measured by altimetric measurements can appear as propagating waves ... 
Study of mechanisms and factors that influence the formation of vortical wake of a heaving airfoil
(American Institute of Physics, 2012)A twodimensional numerical study is performed to investigate the relation between the direction of a deflected wake and the vortex pairing mechanisms. The deflection angle can be correlated with two effective phase ... 
Adaptive and Resilient Flight Control System for a Small Unmanned Aerial System
(Hindawi Publishing Corporation, 2013)The main purpose of this paper is to develop an onboard adaptive and robust flight control system that improves control, stability, and survivability of a small unmanned aerial system in offnominal or outofenvelope ... 
Adaptive Global Carbon Monoxide Kinetic Mechanism over Platinum/Alumina Catalysts
(MDPI, 20130529)Carbon monoxide (CO) oxidation is one of the more widely researched mechanisms given its pertinence across many industrial platforms. Because of this, ample information exists as to the detailed reaction steps in its ...
