Stochastic solution algorithm for Burgers' and Navier-Stokes equation (Master Thesis) (05/2019 – 10/2019)

A wide range of real world problems is formulated in the form of partial differential equations, for example, heat transfer through a solid medium or flow through porous media. Often, these problems are stochastic in nature due to the presence of uncertainty or randomness in the system. In some cases, the mathematical model of the system is not in closed form. To solve such problem, one often uses discretization-based numerical methods such as finite difference or finite volume method. Over the years, many studies have proposed alternative methods. One of such alternatives is the stochastic formulation of a problem and stochastic solution methods. The presence of uncertainty in the problem provides a strong need to consider an approach that incorporates randomness into the numerical method. In this thesis, the stochastic solution algorithms for Burgers and incompressible Navier-Stokes equations are developed. Two approaches, particle-grid and particle-kernel approach, are used for developing the stochastic particle algorithms. These algorithms are demonstrated on one-dimensional Burgers and two-dimensional incompressible Navier-Stokes equations. Convergence studies are performed for each case.
