My Research At A Glance #

My dissertation work is focused on applying high-order spectral element methods to the scale-resolving simulation of high-speed airbreathing propulsion combustors. Specifically I have been working with the Glenn Flux Reconstruction code developed at NASA Glenn Research Center, adding onto its shock capturing capabilities and simulating an experimental dual-mode ramjet combustor from UIUC.

Spectral Element Method #

Spectral elements are a special case of finite elements. Finite-element methods discretize a scalar field into a set of elements, within which the scalar is represented by some function. Most commonly these are polynomial representations; though I have seen some interesting works using things like exponential funtions to achieve faster convergence for boundary layers. Spectral elements are then a subset of finite elements which use polynomials of arbitrary degree to represent the solution, and which are generally discontinuous between neighboring cells. This first picture is a representation of what a few adjacent cells may look like. Notice the discontinuity between elements where they meet.
