The problem of turbulence is certainly one of the well-known “unsolved” problems in mechanics. It has challenged some of the most respected scientists of our times. New physical concepts have thus been invented, and the efforts to understand the problems stimulated the development of elegant stochastic theories.

UNSTEADY COMPRESSIBLE FLOW IN DUCTS
The Quarterly Journal of Mechanics and Applied Mathematics, 1954SUMMARY A rarefaction wave is produced in a two-dimensional channel by the impulsive retraction of a piston. In a finite section of the channel there is a slight variation in cross-section, and the effect of this variation on the rarefaction wave is considered.

In unsteady heat flow problems, in which the temperature T(x, t) depends upon both position x and time t, the balance between heat supply, heat flow and the rate of heat storage must be considered.

On Unsteady Nonlinearized Conical Flow
Journal of the Aeronautical Sciences, 1952It is shown that the equations of unsteady, nonlinear, nonviscous, nonheat-conducting flow may be put in a conical form. The problem of a shock striking an infinite wedge is considered. An invariance relation is established, and certain properties of the reflected shock are examined.
