Conductive Heat Transfer Apparatus P13624 Introduction Purpose Design and construct an apparatus to demonstrate the principles of thermal conductivity to future chemical engineering students Fundamental Idea Temperature Gradient Hot to Cold Customer Project Manager Fielding Confer (CHME) Lead Engineer Dan Unger (CHME) Secretary Robin Basalla (CHME) Specialists Kaitlyn Higgins (CHME) Ryan Murphy (CHME) John Durfee (MECE) Chemical Engineering • Primary Needs • Safe • Accurate • Precise • Educational • Robust • Modular • Reasonable • Testing Time Faculty Sponsors Paul Gregorius KarunaKoppula Team Guide Michael Antoniades Concept Development Final Design • Primary Components • 1 x 18” Cylindrical Specimens: • Aluminum, Copper, Brass • Cartridge Heater • AC Variac • Union Tee • Plastic Tubing • Refrigeration Unit • Wire Thermocouples • National Instruments DAQ • LabView Interface • LabView Programming • Rigid Calcium Silicate • Structured Mineral Wool • Silicone Coated Fiberglass Fabric • Painted Wooden Structure, 20 x 7.5 x 7.5”. Attached Hinges • Specified certain needs of the apparatus as subsystems, separate parts of a whole system • Developed ideas for each subsystem • Compared an array of subsystem configurations and combined benefits of differing concepts • The fundamental concept sandwiched a test specimen between molded insulation and housing • Transmitters and energy in/outputs attach directly • Attempts were made to estimate the maximum dimensions to minimize error Hot Side Cold Side Testing Conclusions • Thermocouples are precise and accurate • The refrigeration unit provides reliable temperatures • The power output from the AC variac follows a fitted model, ; V is the voltage on the variac dial • Fourier’s Law is used to solve for conductivity • Success • Safe • Precise • Robust • Simple • Failure • Lacks needed accuracy • Lengthy experiment • Cumbersome • Potential Improvements • Supplemental cold jacket and tubing to streamline material exchanges • Specimen with thermal conductivity between aluminum and copper • Smaller specimen design for faster testing • Further testing to calibrate the accuracy of the device.
