Scott Speckart

Hometown: Salt Lake City

Program: PhD (Graduated December 2013)

Current Position: Air Dispersion Modeler, Nevada Division of Environmental Protection

Research Interests: My interests include: the examination of atmospheric dispersion both numerically and experimentally. The numerical aspect spans from Lagrangian dispersion models to simpler Atmospheric dispersion models (ADE). Comparing these model results with measurements from the field is very rewarding. My research has implemented these models and methodology to understanding the problem of near source deposition of PM₁₀ generated from traffic on unpaved roads.

I am also interested in the modeling of turbulence. This includes the implementation of simple mixing length models to more complex Large Eddy Simulation (LES). The application of these methods Atmospheric flows to smaller scale engineering flows is of great interest to me.

Announcements

A Final Exam Review will be offered on Friday December 5 from 9-10:30am in EMCB 104.

As a result of this mornings snow storm, Exam 2 has been delayed until Tuesday December 2. All lab reports will now be due on Wednesday December 3. The Fluent Extra Credit is still due on Friday December 5.

I will be showing the Drag video in class tomorrow (necessary for completeing Prelab #6) and giving the lab lecture. (11/11/2003)

Up to date Calendar with all of the remaining important due dates for the rest of the semester (11/10/2003)

Note that the boundary layer video will not be shown in lab sections this week but, rather in class on Wednesday 11/6/2003.

The Moody diagram computer assignment is due on Friday 10/31/2003.

The conversions for Lab#3 are: 2*Volts = inches of H20 (for the pressure transducer) and 1 cm = 1 Volt (for the vertical distance measurement). (10/15/2003)

Grades are now posted on WebCT (10/7/2003)

Exam 1 question number 4 should be resubmitted for homework credit on Thursday 10/9/2003.
