Flow-induced vibration of a web floating over a pressure-pad air bar
(2005-07)
Scope and Method of Study: The aeroelastic (air/web) model is developed by theories of elasticity and fluid dynamics. The flexible web is modeled as a traveling Euler-Bernoulli beam under tension which is exposed to ...
Experimental and theoretical investigation of effect of fin geometry on frost formation on microchannel heat exchangers
(2012-07)
Scope and Method of Study:
Single span web buckling due to roller imperfections in web process machinery
(2006-12)
Scope and Method of Study: To study instabilities in webs resulting from contact with imperfect rollers, whether in their geometry or their orientation in a web span. The instabilities covered include trough formation in ...
2D axis-symmetric wound roll model including nip effects
(2009-12)
Scope and Method of Study: A 2D axis-symmetric wound roll model including nip effects which is based on a pre-stress finite element analysis has been developed. The combined model consists of three interactive sub-models. ...
Higher order and dynamic CFD for aeroelastic simulations
(2011-12)
This dissertation develops and analyzes higher order computational fluid dynamics simulations for coupled fluid-structure interactions as well as large deflection vehicle motions. The flow regime ranges across subsonic, ...
