Computational modeling of extravascular platelet aggregation under flow
… transport algorithm to run in parallel using the FEniCS software suite. We use the numerical tools developed to calibrate and validate an ODE model of extravascular aggregation. With this model, we also benchmark and test the disparity of the fluid and reaction timescales to improve simulation …

Shape optimization for thermoacoustic instability with an adjoint Helmholtz solver
… we solve with the open-source computing platform FEniCS and the library for eigenvalue problems SLEPc. We then derive the formulae for the shape derivatives of the eigenvalues of the Helmholtz equation in Hadamard form for different boundary conditions and in the cases of simple and semi-simple …

Structure-Preserving High Performance Computational Methods for Transport in Porous Media
… libraries and multi-grid solvers like the FEniCS/Firedrake Projects, HYPRE, and Trilinos. It is shown that this spectrum can augment one’s ability to understand both the hardware and algorithmic efficiencies of popular numerical techniques like the finite element method. Second, we propose …

Modelling the floating-catalyst method for carbon nanotube production
Carbon nanotube fiber, as a material, promises superior material properties to ordinary carbon fiber. It has higher tensile strength, as well as high electrical and thermal conductivity. The production process is implemented in several university rigs, as well as in some industrial settings, but …

Timescales of magma residence and transport underneath Iceland
The focus of this thesis is the development and application of a new method of diffusion chronometry known as DFENS (Diffusion chronometry using Finite Elements and Nested Sampling). This method combines a flexible finite element numerical model with a nested sampling Bayesian inversion to provide …
