Explicit finite element analysis of web-roller interaction in web process machinery
(2013-05)
A web can be defined as thin material manufactured and processed in continuous flexible strip form. A web is usually supported, guided and propelled by rollers. In order to make it travel through the process machine line, ...
Galerkin CFD solvers for use in a multi-disciplinary suite for modeling advanced flight vehicles
(2013-05)
This work extends existing Galerkin CFD solvers for use in a multi-disciplinary suite. The suite is proposed as a means of modeling advanced flight vehicles, which exhibit strong coupling between aerodynamics, structural ...
Characterization of cavity wakes
(2011-07)
Scope and Method of Study: This research focused on flow over deep cavities at subsonic speeds with emphasis on the wake downstream of the cavity. Cavity wake behaviors have not been studied in detail and are a major concern ...
Wound-on-tension of winders with nip rollers
(2016-12)
Roll-to-roll (R2R) manufacturing is widely used to create products from traditional web materials such as plastic webs, metal foils, to the recent printed and flexible electronics. Winding or rewinding is a critical component ...
Design and analysis of feedback and feedforward control systems for web tension in roll-to-roll manufacturing
(2015-05)
In Roll-to-Roll (R2R) manufacturing, efficient transport of flexible materials (webs) on rollers requires simultaneous control of web speed and tension. Webs experience disturbing forces during transport due to nonideal ...
Automatic digital holographic analysis of near-field aerated liquid jets in crossflow
(2012-05)
Scope and Method of Study:
Modeling and control of transport behavior of moving webs through heat transfer processes
(2015-07)
Heat transfer processes are widely employed in Roll-to-Roll (R2R) process machines to heat/cool moving webs. The general goal is to efficiently transport webs over heating/cooling rollers and ovens while achieving the ...
Fracture behavior and time dependent properties of poss-epoxy nanocomposites
(2015-07)
This study investigates the fundamental mechanism that governs the influence of glycidyl POSS on the time-dependent behavior of epoxy-POSS composite as a function of added weight percent. Different formulation of POSS-epoxy ...
Effects of ion irradiation on the chemical and microstructural properties of sol-gel derived thin films
(2016-08)
The effects of ion irradiation on the chemical and structural properties of ion irradiated thin films were studied. Ion irradiation was performed using 200 keV H+, 400 keV N2+, 1 MeV Cu+, 4 MeV Cu2+, and 9 MeV Cu3+ ions. ...
Clustering flyash particles using image processing techniques
(2014-07)
Fly ash is one of the residues generated in combustion, and comprises the fine particles that rise with the flue gases. In the US about 43% is recycled and is often used to supplement Portland cement in concrete production. ...
