  • Questions


Problem statement
PROBLEM STATEMENT

Implementing Computational Fluid Dynamics to Investigate Flow Over Complex Topography with Applications to Wind Turbine Sitings and Wind Energy Predictions


Relevance
RELEVANCE

  • Wind Power is one of the most promising and cost effective renewable energy technologies available today

  • Environmental issues negligible compared to current energy sources (I.e. coal, nuclear, gas,..)

  • By 2005: Wind Power Costs = $0.02 per kWh

  • Colorado Potential: 481 billion kWh per year from wind


Methodology
METHODOLOGY

1st Determine a site

  • Alamont Pass, California (East of San Francisco)

  • Tehachapi, California (Kern County)

  • San Gorgonio Pass (North of Palm Springs)

  • Ponnequin Wind Facility, Colorado (N.E. Colorado)


Methodology1
METHODOLOGY

2nd Download that sites .dem file

(Digital Elevation Map)


Methodology2
METHODOLOGY

3rd Convert the .dem to a .vrt & .cel format using FORTRAN (or other operating mode)

- Reformats the given information

- allows us to plot a grid of points


Methodology3
METHODOLOGY

4th Import the data into StarCD

- Creates a surface shell Mesh Grid


Methodology4
METHODOLOGY

5th Determine Boundary/Initial Conditions

& run StarCD program


Methodology5
METHODOLOGY

6th Read output of StarCD and determine highest areas of wind velocity for future wind turbine sitings.


Methodology6
METHODOLOGY

7th Create a program that will determine the energy output from a wind turbine using MATLAB

8th Read output of StarCD into MATLAB to determine energy output of turbines located at different sites.
