Ewald wrote several books on the mechanics of solids and liquids, one of which, The Physics of Solids and Fluids (London, Blackie and Son, 1930) was in collaboration with the physicists Th. Pöschl and Ludwig Prandtl. (Also see Prandtl number, an important dimensionless measure of the ratio of the diffusion of momentum and of heat in fluid dynamics.)
