✦ Synopsis

An experimental investigation has been made for the purpose of studying fluid-mechanical effects on the combustion rate of solid carbon exposed to an oxidizing/'low. The test specimen of solid carbon, the temperature of which was kept constant through each experimental run in the range of 1000 to 1800 °K, was set in the stagnation region of an impinging oxidizing flow and underwent combustion. The velocity of the impinging oxidizing flow was varied in a wide range of 0.61 to 56.7 m/see. It has been found that, throughout the whole experimental temperature and velocity range, the experimental combustion rate can suitably be correlated by expressing the combined chemical and fluid-mechanical effects in terms of the surface Damk6hler number and by reducing the combustion rate to the nondimensional one.

Although combustion reactions of the solid-solid type are not as well-known as gas-solid or gas-gas reactions, they nevertheless are of technical importance. Industrial processes operated in the Soviet Union produce Tic and MoSi, by condensed-phase combustion. This method of synthesis, referred to a

When the total delay time of oxidizer molecules for adsorption, complexing and desorption of reaction products is much less than the mean flight time between collisions a limiting reaction rate is reached which is independent of the properties of the reactant. The total sum of specific gas-kinetic c
