Numerical analysis of fluid flow and heat transfer in a wavy micro-channel

A three-dimensional finite element model was constructed for simulating the steady state flow and heat transfer of a wavy micro-channel. It was hypothesized that adding wave harmonics to a wavy geometry would increase thermal performance. This thesis involves the development, validation, features, and improved topography of said model. The model is solved by the finite element method technique, from which velocity, temperature, and pressure fields are quantifiable, and are used to analyze fluid and geometry interaction. COMSOL Multiphysics, a finite element analysis solver and simulation software, was used to build, solve, and analyze the model. Grid independence was ensured by conducting a convergence test of the model's solution with respect to the model's mesh. Solution accuracy was ensured by comparing our results with those in published literature. End results show that the addition of wave harmonics improved the thermal performance of the wavy micro-channel model nearly two-fold.
