TABLE OF CONTENTS Heat-transfer calculations are often used for thermal analysis and design. The contributors of the five chapters in this part are engineers working at aerospace installations operated by the U.S. government and a university, as well as academics at universities in the United States and Israel. All of the chapters deal with the real world:
Thermal analysis of a large telescope mirror
Cooling a real-size room with a latent-heat-storage unit designed as a shell-and-tube heat exchanger, the tubes of which are filled with a phase-change material
Assuring the operational functionality of a commercial, air-cooled computer used aboard the gondola of a helium balloon at an altitude of 100,000 ft above sea level
Thermal analysis of convectively cooled heat-dissipating components on printed-circuit boards
Design of a fusion-bonding process for fabricating thermoplastic-matrix composites

Telescope mirrors have rather stringent temperature requirements, since a mirror surface that is either hotter or colder than the surrounding air temperature will produce buoyant flows, or seeing, that disturb image quality. In addition, lateral and through-thickness thermal gradients cause mirror substrates to warp by...
