Generalized hydrodynamics

JAN 01, 1984
Efforts to extend ordinary linear hydrodynamics to the microscopic scale have succeeded in predicting, under certain conditions, corrections to Stokes Law and the form of the neutron scattering function.

The object of generalized hydrodynamics is to extend from the macroscopic scale to the microscopic scale the domain in which ordinary hydrodynamics applies. With this extension, under well‐defined conditions, we will then, among other things, be able to predict the momentum with which neutrons are scattered at various angles by the fluid; neutron scattering is one of the principal methods by which the dynamic structure of fluids is investigated experimentally.
