A Numerical Study of Dynamic Micromagnetics
This research work focuses on studying the four micromagnetic fields, exchange field, anisotropy field, demagnetization field and applied field. Based on the related algorithms for programming given, a set of software for micromagnetics calculation is developed successfully in C++. Several attempts …

A numerical study on microbubble mixer
This text comprises a numerical study of the mixing performance on the micromixer, a device which actuates steady streaming by semi-cylindrical sessile bubble oscillations. The mixer's capability of producing chaotic mixing is confirmed and a numerical simulation that is in good agreement with the …

Experimental and numerical study of hypersonic aeroelastic intakes
This thesis investigates the off-design intake operations due to aeroelasticity. An aeroelastic intake was tested in a hypersonic wind tunnel to assess its dynamic flowfield, structural response, and performance. The experiments were informed with static 2D, full-scale static 3D, and fully coupled …

Numerical study of p-wave superconductivity in Sr2RuO4
This thesis contains detailed numerical studies of the superconducting state of Sr2RuO4. This material's magnetic response displays hc=4e periodicity in multiply connected samples, a striking departure from hc=2e periodicity of the Little-Parks effect. One likely explanation for this is that, …
