Abstract

IN each of the processes involved in the study of fluid motion—in observation, measurement, physical explanation, and calculation—this century has seen notable advances. There are improved methods of making the flow visible, and a technique for measurement in thin layers of fluid next to solid boundaries. Enlightenment and understanding have followed recognition of the importance of the motion in such layers, which to some extent has proved amenable to calculation. Such calculations are important mathematical advances; but to most mathematicians the greatest achievements are probably those resulting from skilful use of ideal fluid theory, with circulation and vorticity included. There has been progress in turbulence theory, and in research on compressible fluid flow; and though, on the whole, most attention has been paid to motion past obstacles and in pipes, with their technical applications, it must be remembered that the study of waves and tides has not been without incident in recent years.
