Subsites

I have created other websites that describe current research and/or educational topics. These subsites will describe the specifics involved and provide a number of resources for engineers who wish to learn more. In addition, for those who are using programs that I have created, these websites have downloadable files that can be used in conjunction with the programs.

This website is dedicated to a heat release program developed while a graduate student at the University of Michigan. Analyzing the heat released from fuel during an engine combustion process offers considerable information about its performance and emissions. The goal in calculating heat release is to determine on a crank-angle resolved (or time) basis the energy released by fuel during the combustion stroke of the engine cycle. Since the pressure rise due to combustion inside the cylinder is linked to the fuel energy release (or fuel heat release), one can calculate this energy release by analyzing the cylinder pressure. On this website you can find a number of input files needed for the Graphical User Interface (GUI) version of the program.

This website is dedicated to reacting gas dynamics software created for validation of correct implementation of Computational Fluid Dynamics involving variable properties. In specific, the simulation uses ideal gases with properties depending on chemical composition and temperature. It models the one-dimensional Euler and Navier-Stokes equations with first- and second-order accuracy incorporating friction, heat transfer, area changes and chemical kinetics as source terms. A general framework was created which allows for modeling of all chemical species along with all possible kinetic mechanisms.

I have decided to discontinue this website as I have not been able to get around to updating it and I am wearing many other hats regarding my actual work. In other words, I am too busy to do justice to this site and may revisit it one day when I have more free time.

This website is dedicated to a general catalyst model that I created for my Ph.D. at the University of Michigan. It has been shown in the literature that classical models with simplified representation of the fluid flow through the device have proven their effectiveness in designing catalyst systems that have met emission standards to date. To advance the state of the art in my model, the bulk gas equations have been reformulated based on the governing equations of inviscid flow and full transient capability has been retained. In addition, full variable-property reacting-gas compressible flow (see ) has also been incorporated to compare and contrast the simplified models with the most accurate formulation of the governing equations of motion. The model allows for any type of reaction mechanism, i.e. global or detailed kinetics, to be created and used within the model. This website will eventually include tutorials and downloadable examples for use within the Graphical User Interface and Matlab Simulink versions of the model.

This website is dedicated to a general catalyzed diesel particulate filter model created to complete the set of aftertreatment models for Internal Combustion engines. Similar to my general catalyst model work, I have expanded on the classical literature models in regards to reformulation according to the governing equations of fluid flow including full transient capability. In addition, the chemical species equations and propagation of particulate matter within the device is included in the model. Again, full variable-property reacting-gas compressible flow (see ) has also been incorporated to compare and contrast the simplified models with the most accurate formulation of the governing equations of motion. The model allows for the more traditional particulate oxidation reaction mechanisms to be included along with the ability to model a catalyzed surface. This website will eventually include tutorials and downloadable examples for use within the Graphical User Interface and Matlab Simulink versions of the model.
