Joachim Raabe graduated as a mechanical engineer from the Munich Technical University TUM in 1949 after having been involved in World War II. He submitted to TUM a PhD thesis in 1953 and continued there as an assistant until 1956, when being appointed Lecturer and head of the hydraulic laboratory. From 1958 Raabe was a scientific collaborator of Escher-Wyss in Ravensburg. Raabe was appointed in 1962 professor of hydraulic machinery at TUM, from where he retired in 1988.

During his stay with Escher-Wyss, Raabe took interest in the computational procedures for water hammer, and the design basis for both low pressure turbines and Francis turbines for extremely high heads. Once a professor at TUM he continued researches with an experimental approach, such as on the hydraulic behavior of turbines and centrifugal pumps under unsteady conditions. He was known for his observations on the relative movement of turbine blades by using by then modern instrumentation, such as the hot-film and Laser-Doppler anemometry. Raabe is also known for two outstanding books in hydro machinery. The first published in 1968 relates to the modern machinery available including the plants needed, whereas the 1985 book is an updated version in English that may be considered an excellent contribution to the Anglo-Saxon market, given the relatively small offer. Only recently, Raabe published a third book on a basic method to predict water hammer in relation to Francis turbines.
