  1. The History of Engineering Radiation Heat Transfer John R. Howell The University of Texas at Austin USA

  2. Radiation history begins much earlier than for other modes • Experiments and observations with light • Discovery of the IR, UV spectral regions • Quantifying the basic phenomena (energy vs. T, wavelength, transfer among surfaces) • Engineering applications of the physics

  3. Isaac Newton and the “corpuscular theory” Sir Isaac Newton (1642-1727)

  4. Huyghens disagrees with Newton, proposes light is made of waves Christiaan Huyghens (1629-1695)

  5. Lambert shows the variation of radiation with surface angle Johann Heinrich Lambert (1728-1777)

  6. Sir William Herschel (1738-1822)discovers “invisible light”

  7. Herschel’s Experiment uncovers the infrared spectrum

  8. Nobili and Melloni provide the accurate tools Macedonio Melloni (1798-1854) Leopoldo Nobili (1784-1835)

  10. Kirchhoff describes the relations between surface properties Gustav Kirchhoff (1824-1887)

  11. Stefan and Boltzmann find the Fourth Power Law Josef Stefan 1835-1893 Ludwig Boltzmann 1844-1906

  12. John Ericsson’s Hot Air Engine: after the Monitor John Ericsson 1803-1899

  13. James Clerk Maxwell solidifies EM Theory James Clerk Maxwell 1831-1879

  14. Lummer and Pringsheim measure the Blackbody Spectrum Otto Lummer 1860-1925 Ernst Pringsheim 1859-1917 Lummer-type photometer

  15. Lord Rayleigh, Sir James Jeans and Willy Wien try to derive the blackbody characteristics Wien (1864-1928) Rayleigh (1842-1919) Jeans (1877-1946)

  16. Max Planck ponders the Blackbody Spectral Distribution Max Planck 1858-1947

  17. Comparing classical approaches with the quantum result

  18. Hoyt Hottel initiates Engineering Radiation Heat Transfer Hoyt C. Hottel (1903-1998)

  19. Space-related Thermal Control drives research on radiation

  20. Advanced Propulsion Systems:Solid-Core Nuclear Rockets

  21. Advanced Propulsion Systems:Gas-Core Nuclear Rockets

  22. Continued Development of Solar Energy Applications

  23. Manufacturing processes: IR-Cure-Initiated Filament Winding Tin

  24. Applications Driving Present Research • Advanced manufacturing methods semiconductor wafers, chips, circuit boards, laser- surface interactions • Micro- and nanoscale interactions • Thermal stresses in large-scale structures (space station) • Radiation in large fires and combustion systems • Radiative transfer effects at higher temperatures utility furnaces, jet engines

  25. Applications Driving Present Research (Cont.) • Improved spectral full-field radiative diagnostic techniques • Continued improvement of analytical techniques and experimental and predictive sources for radiative transfer data anisotropic scattering spectral properties
