Roger Curtet graduated as a hydraulic engineer in 1946 from Grenoble University and there submitted in 1958 a PhD thesis. From 1946 he was at its Laboratoires de Mécanique des Fluides, from 1964 as a scientific officer. Curtet was appointed in 1972 professor of fluid mechanics at the University of Grenoble. As a Member of the International Association of Hydraulic Research IAHR from the 1950s he participated in several of its biannual congresses. He was decorated Chevalier des Palmes Académiques from the French government.

Curtet's career may be subdivided in three periods, involving mainly hydraulic model studies until 1953, then a specialization in confined jets and their application to the aerodynamics of flames, and from the 1960s research in rotating fluid flows, twophase flows and the behavior of groundwater flows using the analogy of Henry Selby Hele-Shaw (1854-1941). Curtet's 1967 study on vertically falling air-water mixture flows is a noteworthy contribution with a number of applications in hydraulic and chemical engineering. Following the description of the various regimes in such flows, stable air transport was described and the corresponding friction factors were compared with those of the Moody diagram. Then, unstable air-water flow in vertical pipes was considered as may occur in engineering applications and that may have a drastic effect of a system performance. The study also investigated concentration profiles both in the radial and in the streamwise directions.
