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
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
Prototype Testing
Absorption – with and without cover
Parabolic Bend Angles, Inclination Angle
Fluid Flow Rate
Shutoff Valve Locations
