2D LES CFD Solver

Final project for the CFD course (24718) at CMU.

Objectives

• In our project, we have set out to model the ill effects of having pollution sources in the vicinity of a city. Power plants are a source of constant heat and pollution. While they are designed for maximum thermal efficiency and economy in mind, the long-term health impacts due to pollution should also be taken into account.

• A 2D transient incompressible Navier-Stokes solver was developed in Python that models energy and scalar transport, incorporating buoyancy effects.

• 2D CFD parametric studies were performed on vertical positions of pollutant source and building configurations.

• Our study establishes the need for computational analysis as a tool for policy decisions and regulations for city layouts and power plant locations.

• We have also augmented our solver to solve for turbulent flows in the form of large eddy simulation (LES) based on the Smagorinsky-Lilly model.

Setup

• Computational Domain and Boundary Conditions

• Mesh for the Simulation

Results

• Flow of pollutant around City

• Heat flow around City
