A multiscale study revealing the interplay between tumor growth and the three-dimensional extracellular matrix
Gong, Xiangyu (Rensselaer Polytechnic Institute, Troy, NY, 2019-12)To study biological processes of cancer progression is not an easy task – effort has been made to develop novel in vitro platforms that recapitulate physical features of the tumor microenvironment (TME) for cancer research. ... -
An investigation of the approximate optimal projection reduced-order models for elliptic partial differential equations
Hu, Mingyu (Rensselaer Polytechnic Institute, Troy, NY, 2016-05)Reduced-order modeling is often utilized in obtaining an approximate solution to a complex high-fidelity system. An essential step in constructing a reduced-order system is to project the original high-fidelity system onto ... -

Dynamic load control of a wind turbine blade using synthetic jets
Taylor, Keith Robert (Rensselaer Polytechnic Institute, Troy, NY, 2014-05)This study demonstrated that, through the introduction of periodic momentum near the leading edge of this model, the average tip deflection could be reduced under dynamic conditions. Furthermore, it was demonstrated that, ... -
Effective properties of random composites and fiber networks
Ban, Ehsan (Rensselaer Polytechnic Institute, Troy, NY, 2015-12)Random fiber networks are assemblies of one-dimensional mechanical elements used to model the mechanics of various natural and man-made materials such as biopolymer gels and synthetic nonwovens. The small-strain mechanics ... -
Error-driven and predictive mesh control for adaptive simulations of incompressible two-phase flows
Zhang, Alvin (Rensselaer Polytechnic Institute, Troy, NY, 2019-12)adaptive approach becomes highly desirable. This is particularly the case for two-phase flows where interface evolution and dynamics are of interest. -
Flow physics and sensitivity study of synthetic jets-based flow control of 3-D configurations
Monastero, Marianne C. (Rensselaer Polytechnic Institute, Troy, NY, 2018-05)Bridging the gap between sub-scale, fundamental studies of synthetic jet actuators on aerodynamic models and full-scale applications on actual vehicles requires a thorough understanding of how the synthetic jets interact ... -
Mathematical modeling of wildfire dynamics
Del Bene, Kevin (Rensselaer Polytechnic Institute, Troy, NY, 2013-12)Wildfires continue to pose a long-standing threat in our society. In this thesis, I derive and solve a fluid dynamics model to study a specific type of wildfire, namely, a two-dimensional flow around a rising plume above ... -

Ban, Ehsan (Rensselaer Polytechnic Institute, Troy, NY, 2012-08) -
Mechanistic modeling of nucleate boiling
Wang, Zeyong (Rensselaer Polytechnic Institute, Troy, NY, 2017-12)The existing nucleation site density models assume that boiling occurs when the wall temperature reaches the fluid saturation temperature. This assumption is not consistent with the fact that wall superheat of a few degrees ... -
Novel residual-based large eddy simulation turbulence models for incompressible magnetohydrodynamics
Sondak, David (Rensselaer Polytechnic Institute, Troy, NY, 2013-08)The goal of this work was to develop, introduce, and test a promising computational paradigm for the development of turbulence models for incompressible magnetohydrodynamics (MHD). MHD governs the behavior of an electrically ... -
