CHANG-LIN TIEN’S CONTRIBUTIONS IN ENERGY SYSTEMS

A brief review summarizing the contributions of Chang-Lin Tien to the field of energy systems has been presented. Since much of his relevant work is described elsewhere in this volume, only his treatment of superconducting systems, and of solar energy systems, is described here. The superconductivity work started in 1969 and spanned a total of 23 years, including both low-temperature and high-temperature superconducting systems. For solar energy, his first publication was in 1975, and he and his colleagues continued to publish work emphasizing natural convection-both in enclosures and in cavities-until 1986, a total of 11 years worth of work. His contributions to the analysis, design, and control of energy systems, however, includes his huge body of work in radiative heat transfer, thermal insulation, heat transfer in porous media, phase-change heat transfer, and all of the other fields in which he took an interest.
