Design of a Solar Collector For a Trochoidal Gear Engine Fall Progress Report Amy Manganello Advisor: Prof. Richard Wilk
Accomplishments • Problem definition (spring ’05) • Familiarize myself with principles of solar energy and collector design (weeks 1-5, ongoing) • Produce design options (weeks 7/8) • Choose design/Make SolidWorks model (week 9) • Proposal, IEF, presentation, report (ongoing)
A Trochoidal What??? • Ener-G-Rotors designed a TGE • Rankine Cycle • Reduced contact friction • Lowers input temperature • Solar thermal power a possibility • Design Specifications • Temperature input, T = 170°F • Power input, P = 35.2 kW • Manufacturability, Cost, Size http://www.easa.com/indus/stator11.html
Collector DesignA Basic Flat-Plate Collector http://www.nemmar.com/images/i03/ESHI-solar-power-image2.jpg
Collector Optimization • Concentrating Collectors • Focus sunlight = high temperatures • Shape, reflection, lenses, and tracking systems • Insulation • Transparent: prevents losses from the absorber • Opaque: prevents losses from the back and sides of the collector body http://www.powerfromthesun.net/chapter1/Chapter1.htm
Design Options: Parabolic Trough Collector Advantages: • Shape focuses light onto absorber Disadvantages: • If Fresnel lenses are used, shape is unnecessarily complex
Design Options: Dish Collector Advantages: • Focuses light to a point Disadvantages: • Difficult to make • Costly
Design Options:Enclosed Flat Plate Collector w/ Fresnel Lenses Advantages: • Simple/Easy to manufacture • Focuses light using Fresnel lens • Double cover insulates Disadvantages: • Will the temperature equalize across the area of the plate? ***Design Chosen to Test
Prototype Design • Two lenses deep, one wide • Two covers for insulation • Ten copper pipes (3/4’’ diameter) • Aluminum body surrounded with insulation
Future Goals • Build and test prototype • Thermal analysis in SolidWorks • Finalize design/build SolidWorks model • Order parts • Build full scale model • Modify and optimize
