Hyperbolic Solar Collector Bader Al Ojairi Abdullah alsenawi George Milne Team 07 EML 4551 Ethics and Design Project Organization FIU Department of Mechanical Engineering Miami, Florida

Problem Statement Hyperbolic 3-D design replaces the control system that tracks the sunlight. Combined effect of Conduction, Convection, and Radiation. Use concentrated sunlight located at the focal point for maximum radiation absorption.

Motivation Availability of fossil fuels is decreasing, leading to high demand for renewable Reduce dependency on imported energy such as crude oil Reduce environmental impact of fossil fuel consumption and harvesting

Previous Designs

Proposed Design Copper is a good heat absorber Helical copper tube will be heated by conduction and convection Concentrated sunlight is used to heat up the tubes by radiation Glass helps retaining solar radiation inside the system to increase the efficiency

Alternative designs Use Reflected mirror or parabolic dish Preheated water accelerates heating process Provides higher steam temperature and pressure
