Об авторе книги Basic heat transfer

Frank Kreith, author of Basic Heat Transfer, was a pioneering mechanical engineer and renewable energy expert whose work shaped thermal science education and sustainable energy research.

A professor emeritus at the University of Colorado Boulder, Kreith combined academic rigor with real-world application, having contributed to rocket engine heat transfer at NASA’s Jet Propulsion Laboratory and led solar energy research at the National Renewable Energy Laboratory (NREL). His seminal textbook Principles of Heat Transfer became a cornerstone of engineering curricula, praised for bridging theoretical concepts with practical solutions for energy systems.

Kreith’s expertise extended beyond academia—he advised policymakers as a National Conference of State Legislatures Fellow and co-authored influential works on sustainable energy, including Principles of Sustainable Energy Systems. Honored with the ASME Frank Kreith Energy Award for lifelong contributions to renewable energy, his research remains foundational in engineering.

Kreith’s legacy endures through his mentorship of generations of engineers and his role in establishing the ASME Journal of Solar Energy Engineering, which he co-founded and edited.
