Adrian Bejan (24 September 1948, Galaţi, Romania) is an American professor and proponent of the constructal theory of design and evolution in nature. He is J. A. Jones Distinguished Professor of Mechanical Engineering at Duke University.

Early life

Adrian Bejan was born on 24 September 1948, in Galaţi, a port town located at the Danube in Moldavia, Romania. His mother, Marioara Bejan (1914-1998), was a pharmacist. His father, Dr. Anghel Bejan, was a veterinarian. Bejan showed an early talent in drawing and his parents enrolled him in art school. He also excelled in basketball, which earned him a position on the Romanian national basketball team. As a member of that team he traveled to Bulgaria and Hungary. At age 20 he participated in a math competition. The top six finalists were awarded an application form for an American university. Bejan was allowed to apply for admission to the Massachusetts Institute of Technology. He was accepted in December 1968 and was allowed to leave for the united States in February 1969 at a time when travel was severely restricted by the communist government of Romania.

Education

Adrian Bejan received all his degrees from MIT: BS 1971 (Honors Course), MS 1972 (Honors Course), and PhD in 1975, all from the Department of Mechanical Engineering at MIT.

During 1976-1978 he was a Miller Fellow at the University of California Berkeley, in the Miller Institute for Basic Research in Science.

Bejan was appointed full professor with tenure at Duke University in 1984. He was awarded the J.A. Jones distinguished professorship in 1989.

Scientific career

Bejan has published 530 peer-reviewed articles and 24 books. He pioneered numerous original methods in science, such as the constructal law of design and evolution in nature, entropy generation minimization, scale analysis of convection, heatlines and masslines, transition to turbulence, and designed porous media.

He is listed among the top 100 most widely cited engineering authors in the world (all disciplines, all countries, living and deceased).

He was awarded 16 doctorates Honoris Causa from universities in 11 countries.

Bejan numbers

  • Bejan number (Be), proposed as name for the dimensionless ratio of fluid friction irreversibility divided by heat transfer irreversibility, in convection (S. Paoletti, F. Rispoli and E. Sciubba, Calculation of exergetic losses in compact heat exchanger passages, ASME AES-Vol. 10-2, 1989, pp. 21–29).
  • Bejan number (Be), proposed as name for the dimensionless group ΔP·L / (μα) in forced convection, electronic cooling, contact melting, and second law analysis of heat transfer (S. Petrescu, Int. J. Heat Mass Transfer, Vol. 37, 1994, p. 1283).
