I have worked on quite a variety of projects over the past 40+ years. The following is a selection of those projects for which there is some colorful illustration. They are arranged in no particular order.
Computational Fluid Dynamics, Thermochemical Reactions, Thermodynamic and Transport Properties of Fluids, Complex Variables, Evaporative Cooling Towers , Novel Ways of Displaying Data, Digital Terrain Models, Mass Transfer
I provided technical support to build this model of a group of leach ponds contaminated
with Thorium: ThoriumPonds
Some
of the algorithms I have developed have also been useful in unrelated
fields, for instance, I was able to adapt the field interpolation
algorithm I developed for contaminant plumes to enhance the search for
unexploded ordinance at this military site: EOD WalkDown
I have developed complete heat rejection system models for several nuclear and coal-fired power plants: PowerPlants
I also did a detailed thermal and hydraulic study of the multi-port diffusers at the Browns Ferry Nuclear Plant, through which the waste heat is discharged into the Tennessee River at about 2,000,000 gpm or 128 m²/s. The three diffusers are 17, 19, and 20.5 ft in diameter and 1010, 1610, and 2210 feet long. Here are several 3D animations I created as part of the study: BFN Diffusers
While I'm not a geohydrologist, I have provided the technical and modeling support for dozens of such projects, which often involve contaminant plumes, as illustrated here: Contaminant Plumes As part of this work I developed a three-dimensional contaminant transport model builder: 3D Model Builder As part of my work on contaminant transport, I developed an advanced particle tracker, which is described here: Particle Tracker which, among other things, creates technically accurate animations of contaminant transport, as illustrated here: Contaminant Transport Animations
One of the more interesting types of transport simulation is: Flow in Fractured Media
I also
used particle tracking to identify the most likely mosquito breeding
locations in Zambia, a country plagued by the scourge of malaria: Mosquitoes in Zambia
While I
am by no means a water quality expert, I have often served as an
applied mathematician, providing a wide range of computer modeling for
colleagues having diverse specialties, including: Water Quality Modeling
Complex grids are an important part
of any three-dimensional model. These can vary considerably in shape
and detail, as illustrated here: Grids and also here: GridGeneration
I have also developed several interactive three-dimensional computer models of actual systems that have been used for a variety of things, including training, inventory, and analysis: 3D Models
Bringing
data together from multiple sources and creatively displaying it can
often reveal interactions that were not previously evident, as in this animation of mining operation near a virgin forest: Mining Operation
Accurately determining the hydraulic properties of the ground can also be a challenging problem, as described here: WellTest
Some examples using the finite element method for plane strain/stress as described in the text Differential Equations can be seen here finite elements.
The risk of icing is of great concern when operating a gas turbine: risk of icing
Another very interesting project I did was modeling a flood in a major city: flooding
