  1. BOAT HANDRAIL HEATING SYSTEM Group 11 Oscar Garcia Nik Hartney Pamela Mills Nicole Turner

  2. Boat Hand Rails • Used to provide a secure handhold • Exposed to external weather conditions • Susceptible to temperature changes • May become uncomfortable to hold

  3. Heating System • Allows passengers to remain secure • Provides comfort • Helps prevent frostbite

  4. Design • Needs to run off of minimal energy • Versatile enough to be applied to any boat with an inboard engine • Must have a controllable temperature as to not overheat or remain too cool

  5. Heating Fluid Handrail Pump Sea Water Feed Resistive Heater + - Electrical Source Alternate Designs • Electrical resistance heater • Seawater coolant heat exchanger Heat Exchanger

  6. Handrail Seawater Exhaust Final Design • Raw seawater coolant flowing directly through handrail • Harnesses waste thermal energy • No need for complex electrical system

  7. Design Specifics • Dual opposing flows to regulate average temperature • Thermally conductive fluid conduit • Variable throttle for seawater coolant intake • Open fluid system • Piping system insulation

  8. Computations and Testing • System parameter assumptions Trail = 27C Tatmosphere = -20C Drail = 2 inches = 0.051m Vwind = 20 mi/h = 8.94m/s Texhaust=92 C • External Forced convective heat transfer

  9. Computations and Testing • Handrail heat loss per meter

  10. Computations and Testing • Log mean temperature difference

  11. Computations and Testing • Mass flow rate and Velocity of seawater

  12. Cost Analysis • Piping material selection: inexpensive, conductive • Connections and Valves • External thermometer

  13. Conclusion • Provide a temperature controlled railing system • Minimal impact on boat’s systems • Allow comfort and security for boat passengers
