Biography

Chu received a bachelor's in mechanical engineering from Chiao-Tung University in 1948, a master's from Cornell University in 1950, and a Ph.D. from Courant Institute, New York University in 1959.[1]

Chu was an internationally recognized applied mathematician and one of the pioneers of computational mathematics in fluid dynamics, magnetohydrodynamics, and shock waves. He developed approximations to the differential equations of fluid dynamics and coined the term "computational fluid dynamics".[2]

Chu received numerous honors. He was a recipient of Guggenheim Fellowship and was elected fellow of American Physical Society and fellow of Japan Society for the Promotion of Science. He was awarded an honorary Doctor of Science degree from Columbia University in 2006.[1][2]

Chia-Kun Chu was the son of bank chairman Ju Tang Chu.[3] Chia-Kun Chu was also the brother-in-law of Z.Y. Fu, a Columbia donor who gave his name for the Fu Foundation School of Engineering and Applied Science.[4]

Chia-Kun Chu died on January 2, 2023, at the age of 95.[5][6]
