The Icing of Aircraft (open access)

The Icing of Aircraft

This technical memorandum presents a theoretical study of the processes accompanying the formation of ice on solid bodies. It discusses vapor pressure and sublimation in two air masses separated by a boundary area.

Thermal Theory of Combustion and Explosion 3: Theory of Normal Flame Propagation (open access)

Thermal Theory of Combustion and Explosion 3: Theory of Normal Flame Propagation

The technical memorandum covers experimental data on flame propagation, the velocity of flame propagation, analysis of the old theoretical views of flame propagation, confirmation of the theory for simple reactions (theory of combustion of explosive substances and in particular nitroglycol), and check of the theory by example of a chain oxidizing reaction (theory of flame propagation in carbon monoxide, air and carbon monoxide - oxygen mixtures).

The Navier-Stokes Stress Principle for Viscous Fluids (open access)

The Navier-Stokes Stress Principle for Viscous Fluids

"The Navier-Stokes stress principle is checked in the light of Maxwell's mechanism of friction and in connection herewith the possibility of another theorem is indicated. The Navier-Stokes stress principle is in general predicated upon the conception of the plastic body. Hence the process is a purely phenomenological one, which Newton himself followed with his special theorem for one-dimensional flows" (p. 1).
