Projects

Below are some of the projects I have done for school along with a few of my individual pursuits.

 

CFD of Lid Driven Cavity As a final project for my CFD course at Virginia Tech, I wrote a C++ implementation of the lid driven cavity problem. This report goes through the discretization of the governing equations and how the solver works and some investigations into solver stability. Click on the image for the full PDF of the report.
Moment Area of Inertia Calculator This small MATLAB script will calculate the moment of inertia of any shape based on an image of the shape. It will then calculate the Ix and Iy values as a function of rotating the shape through a 90 degree arc. Click on the image for the source code as well as an example.
Heat transfer analysis of heat sink This Power Point presentation comes from a project that I did for my heat transfer course at BYU. I compared the results for analyzing a computer heat sink obtained via ANSYS to those obtained via hand calculations.
Compressible flow with combined friction and area change This MATLAB script will calculate the Mach number change and total pressure change through a duct or nozzle with changing area as well as friction. Click on the image to download the source code as well as an example.
Analysis of Westinghouse J-30 Turbojet I wrote this report as part of my propulsion class at Virginia Tech. In the report I analyze a Westinghouse J-30 engine using the commercial software package GasTurb and compare the results to the published specifications of the engine.

High Speed Video of Milk Drop As part of my instrumentation course, I designed a trigger to work with our high speed camera. This circuit interfaced with the camera to trigger it in time with a droplet of milk falling into a beaker. The question we were trying to answer was whether the jet from a drop of chocolate milk falling into a glass of regular milk would be chocolate or regular. See the video on the right for the results.
Air Powered engine This video shows an air powered engine that I built for my manufacturing class at BYU. I machined most of the parts myself in the metal shop.
CAD Model of a Computer Fan This picture illustrates a CAD model of a computer fan that I did for my engineering graphics course at BYU. This was the first part that I modeled for the course, using Pro Engineer, CATIA, and NX. This picture comes from my NX model of the part.
ScanMySlides I built this business which specializes in scanning 35mm slides from the ground up. You can read more about it on my resume or on the site itself.
Maxwell Institute For a job that I had on campus at BYU, I built this site by myself over the course of 10 months, completely re engineering how people access the journals that the Maxwell Institute publishes. You can see some of the things that I made by going directly to the site.
Parametric CAD model of a Food Chopper This picture shows a parametric CAD model of a food chopper that I made for my engineering graphics course at BYU. For this model I used NX 5. I was able to create the model so that I could easily update the rest of the chopper according the one dimension that I changed. As you can tell from the photo, I chose to have the handle remain the same size and varied the size of container holding the food since the size of things being chopped could vary greatly, from cashews to cantaloupe, but the size of a human hand is more constant.
