Question: Who founded a peer-reviewed scientific journal in the field of fluid mechanics?
Context: The Zeitschrift für Angewandte Mathematik und Physik (English: "Journal of Applied Mathematics and Physics") is a bimonthly peer-reviewed scientific journal published by Birkhäuser Verlag.  The editor-in-chief is Kaspar Nipp (ETH Zurich).  It was established in 1950 and covers the fields of fluid mechanics, solid mechanics, differential equations/applied mathematics, and related topics.  According to the "Journal Citation Reports", the journal has a 2012 impact factor of 0.938. The International Journal of Multiphase Flow is a monthly peer-reviewed scientific journal covering fluid mechanics.  The editor-in-chief is Andrea Prosperetti (Johns Hopkins University).  The founding editor was Gad Hetsroni (Technion – Israel Institute of Technology). Fluid mechanics is a branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them.  Fluid mechanics has a wide range of applications, including mechanical engineering, civil engineering, chemical engineering, biomedical engineering, geophysics, astrophysics, and biology.  Fluid mechanics can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion.  It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a "macroscopic" viewpoint rather than from "microscopic".  Fluid mechanics, especially fluid dynamics, is an active field of research with many problems that are partly or wholly unsolved.  Fluid mechanics can be mathematically complex, and can best be solved by numerical methods, typically using computers.  A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach to solving fluid mechanics problems.  Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow. Annual Review of Fluid Mechanics is a peer-reviewed scientific journal covering research on fluid mechanics.  It is published once a year by Annual Reviews and the editors-in-chief are Stephen H. Davis (Northwestern University) and Parviz Moin (Stanford University).  According to the "Journal Citation Reports", the journal has a 2014 impact factor of 11.163, ranking it 1st out of 139 journals in the category "Mechanics" and 1st out of 31 journals in "Physics, Fluids and Plasmas". George Keith Batchelor FRS (8 March 1920 – 30 March 2000) was an Australian applied mathematician and fluid dynamicist.  He was for many years the Professor of Applied Mathematics in the University of Cambridge, and was founding head of the Department of Applied Mathematics and Theoretical Physics (DAMTP).  In 1956 he founded the influential "Journal of Fluid Mechanics" which he edited for some forty years.  Prior to Cambridge he studied in Melbourne High School. Flow, Turbulence and Combustion is a peer-reviewed scientific journal on fluid mechanics.  It covers original research on fluid mechanics and combustion, with the areas of interest including industrial, geophysical, and environmental applications.  The journal was established in 1949 under the name Applied Scientific Research.  It obtained its present name in 1998, which also reflects its association with the European Research Community on Flow, Turbulence and Combustion (ERCOFTAC). The Journal of Fluid Mechanics is a peer-reviewed scientific journal in the field of fluid mechanics.  It publishes original work on theoretical, computational, and experimental aspects of the subject. Gianni Pedrizzetti (7 September 1963 in Prato, Italy) is an Italian engineer who is a professor in fluid mechanics at the University of Trieste.  His research is the application of fluid mechanics to improve cardiovascular sciences.  He introduced optical flow techniques for the benefit of obtaining dynamic information from medical images, with the goal of improving heart diseases diagnostics.  Pedrizzetti has published over 60 articles on peer-reviewed international journals, and is co-inventor of several patented solutions in the field of medical imaging and medical data processing.  He is an author of a monograph which relates basic theoretical principles in bioengineering and fluid mechanics to the cardiovascular problems and medical solutions.  He represents a purely interdisciplinary scientists bridging theoretical, experimental and numerical analysis to actual applications in clinical cardiology. Fluid Dynamics Research is a bimonthly peer-reviewed scientific journal covering all fields of fluid dynamics.  It is published by IOP Publishing on behalf of the Japan Society of Fluid Mechanics.  The editor-in-chief is Yasuhide Fukumoto (Kyushu University).  According to the "Journal Citation Reports", the journal has a 2014 impact factor of 0.990. The Journal of Experiments in Fluid Mechanics is a bimonthly peer-reviewed scientific journal covering fluid dynamics.  It was established in 1987 and is published by the China Aerodynamics Research Society.  The editor-in-chief is Jialing Le.  The journal publishes articles in Chinese and English.
