Combustion study of a multi-point ground flare system using CFD, Assisted the code author Dr. Ahti Suo-Anttila test a “multi-block” (to run a single problem on multiple processors) variant of the Sandia Labs CFD code C3d on a large multi-point flare field system. Furthermore, the effects of wind, and radiation from this field on nearby structures/locations was determined.
Design and CFD validation of novel sparger design for crossflow mixing, With the commercial CFD code ANSYS FLUENT, a sparger/distributor was designed to target specified pressure drop in an air duct crossflow while maximizing mixing.
NOx and CO reduction with CFD analyses of single-burner and full furnace models (wall-fired) using natural gas, Using the commercial CFD code ANSYS FLUENT, improvements were sought in NOx and CO reduction as compared to a prior burner and full furnace upgrade study. This study was completed at MS&T, Rolla.
Combustion study of a multi-point ground flare system using CFD, Using the Sandia Labs developed CFD code C3d (maintenance and updation by Dr. Suo-Anttila), a large multi-point flare field system was analyzed, and the effects of radiation from this field on nearby structures was determined. This study was completed at MS&T, Rolla.
Development of a CFD Model for Gasification of Biomass with Arbitrary Shape Deformation using Sculptor(TM), Building on prior CFD work with ANSYS FLUENT, a parametric study with variation of secondary air inlet sizes, locations and combustor shape were tried out using Sculptor(TM).
CFD Model Development for an Entrained-Flow Type Woody Biomass Gasifier, Using ANSYS Fluent 14.5 an Euler-Lagrange CFD model was developed for an air-blown, downdraft entrained-flow woody biomass gasifier and the model was validated with experimental results.

October 2013 to April 2014
CFD Validation and Parametric Study of Existing Coal-Fired Power Plants for Nox and CO Mitigation – Based on CFD analysis and modification with low-NOx/ultra low-Nox SAS burners, design changes were suggested for existing plants (West Burton and Cottam in the UK) to meet future emission requirements (targeted low Nox and carbon in ash). An Euler-Lagrange (discrete phase method) model utilizing a competing eddy-breakup and finite rate chemistry model was refined for this purpose. The parametric study for the plant upgrades is ongoing using FLUENT.
Vapor and Steam Separator – Multiphase Eulerian models with population balance equations were developed to represent droplet size (with breakup and agglomeration). FLUENT 13/14 was used for modeling purposes. This study was completed in Rolla (post-doctoral study) and as an intern in Tulsa (for SAS).
