Doctor of Philosophy (PhD)
Engineering Science (Interdepartmental Program)
This dissertation is divided into two parts. The first part includes chapter 2 to 4, which focus on development and application of numerical algorithm on particle and fluid simulation. Starting with a pure granular system in a driven cavity setup (Chapter 2), we move on to the immersed boundary simulation of fluid solid interaction (Chapter 3). This part ends with a coupled immersed boundary-discrete particle implementation. The second part includes Chapter 5 and Appendix A, each deals with an independent problem and focuses more on the theoretical aspects. Chapter 5 deals with a classic fluid dynamics problem of thermal wave induced net flux. Appendix A studies the underestimation of solver accuracy when the solution has singularities, and analyzes the cause of the underestimation using a simple theoretical model.
