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 ...
Enhanced Vertical Ground Heat Exchanger Model for Whole Building Energy Simulation
(2019-07)
The U.S. Energy Information Agency estimates that buildings consume more than 40% of all energy used in the United States. This includes considering energy used for transportation and heavy industry. As a result, many ...
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 ...
Mechanics of Winding Laminate Webs and the Prediction of Machine Direction Curl
(2019-05-01)
Winding models that describe the residual stresses due to winding single layer webs at the end of roll-to-roll manufacturing machines began development over 50 years ago. These models have been used to reduce or avoid ...
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 ...
