Computing the Effective Hamiltonian in the Majda-Souganidis Model

Abstract

<p> In premixed turbulent combustion, the normal speed of propagation of the flame front is enhanced by the turbulent velocity field. This project will focus on the method of computing the normal speed of propagation of the flame front in the Majda-Souganidis model of turbulent combustion. Solving this problem involves computing the eigenvalue of a nonlinear cell problem. Discussed in this thesis is a new, simple and direct numerical method for approximating the eigenvalue, also called the effective Hamiltonian.</p>
