Towards Cfd Investigations Into Particulate Air Pollution Of A Desert Urban Environment, Prosun Roy
Towards Cfd Investigations Into Particulate Air Pollution Of A Desert Urban Environment, Prosun Roy
UNLV Theses, Dissertations, Professional Papers, and Capstones
This dissertation has explored computational fluid dynamics (CFD) techniques for studying particulate air quality in the Las Vegas urban area. The dissertation is based on three research tasks:
- • High time-resolution fenceline air quality sensing and dispersion modeling for environmental justice-centered source attribution. (Chapter 2)
- • Pollen dispersion and deposition in real-world urban settings: A computational fluid dynamic study. (Chapter 3)
- • Effects of urban canopy parameterizations on modeling pollen dispersion and exposure. (Chapter 4)
In Chapter 2, we investigate the facilitation of low-cost air quality sensors (LCAQS) and CFD technique on exposure assessment of environmental justice (EJ) communities and …
A Computational Fluid Dynamic Analysis Of Oxyacetylene Combustion Flow For Use In Material Response Boundary Conditions, Craig Meade
Theses and Dissertations--Mechanical Engineering
Oxyacetylene torches are used in the aerospace industry and research to test thermal protection system materials (TPS) due to their high flame temperatures and high heat flux capabilities. The purpose of this work is to determine a combustion model to accurately simulate the high temperature flow of an oxyacetylene torch. The flow conditions around a sample material can then be used as boundary conditions when modeling TPS material response. Two separate combustion models with equilibrium chemistry were investigated using ANSYS Fluent™; the Eddy-Dissipation Model, and the Partially Premixed model.The results of this study are compared to existing experiments for validation.
