Flow Through a Catalytic Reactor
16 May 2019 | | Contributor(s):: Adam Powell
Use porous flow theory to describe pressure-flow rate and plug/mixing behavior of flow through a packed bed of catalyst spheres.
Dimensional Analysis: Catalytic Combustion of Carbon Monoxide
Use dimensional analysis to understand how parameters and material properties determine uniformity of reactant gas concentration across porous spheres coated with catalysts.
Freezing by Radiation and Convection
Use radiation and a heat transfer coefficient to estimate the initial rate of solidification of the solid shell at the top of a casting while the temperature in the shell can be considered uniform, then set up the equation for mixed conduction/convection-radiation limited cooling.
Heat Conduction and Diffusion in Alloy Casting
Derive temperature and liquid concentration profiles during die casting of a roughly plate-shaped alloy part.
CD Injection Molding I: Navier-Stokes
10 Apr 2019 | | Contributor(s):: Adam Powell
State simplifying assumptions which can be made regarding radial injection molding of liquid polycarbonate polymer into a CD mold, and simplify the cylindrical form of the Navier-Stokes equations accordingly.
CD Injection Molding II: Shear Stress
09 Apr 2019 | | Contributor(s):: Adam Powell
Solve the cylindrical Navier-Stokes equations simplified in Part I to give the velocity profile in radial injection molding of a CD, and calculate the shear stress based on this velocity profile.
Radiative Cooling of an Aluminum Cube
Show that radiative cooling of an aluminum cube is Newtonian (uniform temperature), and calculate time required to cool through a certain temperature range by radiation alone.
Bottom Filled Mold
07 Apr 2019 | | Contributor(s):: Matthew John M. Krane
Calculation of mold filling times, with and without a constant height of metal in a riser. Problem uses modified Bernoulli equation for the mechanical energy balance and the students are asked to determine which resistances are significant.
Cast-a-Box: Casting Conditions and Macroporosity
07 Apr 2019 | | Contributor(s):: Adam Powell
An illustration of three-dimensional finite difference simulation of heat conduction with phase change and complex boundary conditions, this requires students to adjust boundary conditions to make the top surface of a regular hexahedral "casting" to freeze last, eliminating...
Batch and Continuous Flow Reactors
30 Mar 2019 | | Contributor(s):: Adam Powell
Derive expressions for productivity of plug flow and perfectly mixed continuous flow reactors, discuss quality, and describe advantages of batch reactors.
30 Mar 2019 |
Estimate flow rate of blood through two types of porous filter: an array of tubes and a packed bed of solid spheres.
Blood Flow and Vascular Deposits
Analyze the effect of increasing fat deposit thickness on blood flow through human arteries.
Casting of a Cylindrical Part in a Thermally Resistive Mold
30 Mar 2019 | | Contributor(s):: Matthew John M. Krane
Use of integral analysis for development of approximate solution for solidification in cylindrical thermally resistive mold.
A Heat Transfer Calculation

Nanotechnology and the NAE Grand Challenge Reverse Engineer the Brain
14 Aug 2017 | | Contributor(s):: Edward Davis, Virginia Davis, Joni Lakin
This group of materials is designed to provide a framework to teach students in an introductory engineering course basic nanotechnology concepts. The materials use the NAE grand challenge “Reverse Engineering the Brain” to underpin the need and potential for nanotechnology to address...
Engineering Career Profiles
10 May 2017 | | Contributor(s):: Tamecia Raishaun Jones
Although there are many programs and curriculum opportunities for students to do engineering projects, surveys from middle and high school students have said that they are interested in what engineers do from day to day. We have interviewed scientists and engineers who do...
Measuring the Impact of Service-Learning Projects in Engineering: High School Students' Perspectives
10 May 2017 | | Contributor(s):: Tamecia Raishaun Jones, Jean M Trusedell, William "Bill" C. Oakes, Monica Elaine Cardella
We have seen the benefits of service learning and its impact on perceptions and knowledge of engineering and recognize it as a successful mechanism for introducing often highly abstracted concepts to younger students. This paper describes the analysis of student reflections from...
