During the 1930s, the HYD continued to be active in not only the traditional areas of hydraulics, namely, turbine and pump design and performance, but also emerging problems of water hammer, surge tank simulation, and cavitation. Theodore von Kàrmàn, (Fig. 5) after arriving at Caltech during 1930, continued to enhance the understanding of turbulence and its effect on fluid resistance, as well as to advise his colleagues in their research endeavors; the main recipient being Robert T. Knapp (Fig. 6), to be referred to later. Of note is the fact that von Kàrmàn received the ASME Medal for his contributions to a vast array of fluid mechanics problems.
So the Fluids Engineering Division Executive Committee (FEDEC) at their meeting in late 1989 proposed a review that would ensure better coordination of their committees and would increase participation of the industrial members of the Division in its technical programs. This would address three trends that characterized the new landscape, namely, (a) the increase in fluids engineering industrial applications in addition to traditional fluid machinery (pumps and turbines), (b) a fusion of the disciplines of that traditional fluid machinery area, and (c) increased research in basic flows in the fluid mechanics discipline.

In the early 1900s, workers such as Prandtl, Rayleigh, and Reynolds combined theory and experiment into a single discipline, fluid mechanics. In the ensuing century, mechanical engineers have developed the practical and design aspects of fluid flow into a very successful discipline.
Figure 2.1 (shown right) represents the aero-thermo domain of turbomachinery. The horizontal axis represents the energy equation derivable from The first law of thermodynamics.[1][14] The vertical axis, which can be characterized by Mach Number, represents the range of fluid compressibility (or elasticity).[1][14] The Z-axis, which can be characterized by Reynolds number, represents the range of fluid viscosities (or stickiness).[14] Mathematicians and physicists who established the foundations of this aero-thermo domain include:[15][16] Isaac Newton, Daniel Bernoulli, Leonhard Euler, Claude-Louis Navier, George Stokes, Ernst Mach, Nikolay Yegorovich Zhukovsky, Martin Kutta, Ludwig Prandtl, Theodore von Kármán, Paul Richard Heinrich Blasius, and Henri Coandă. 2ff7e9595c
