Available in PDF, EPUB and Kindle. Book excerpt: One method of solving the problem of burning or combustion at supersonic speed is by combusting in a stationary detonation wave. Stabilization of a detonation wave has been recently accomplished and is reproducible, but only in laboratory type apparatus. Using two-dimensional steady flow, perfect gas theory, this paper provides solutions for the changes in properties that may be expected across any oblique detonation wave. Equations are established and solved using the Control Data Corporation 1604 digital computer of the U.S. Naval Postgraduate School, Monterey, California, for different values of specific heat ratio, initial Mach number, a function of the flow deflection angle, and the amount of heat added in the detonation. The results appear in tabular form and for several specific values of Mach number and heat addition in graphical form. An example of use of the data is shown with reference to a ramjet engine operating with a stationary detonation wave for the combustion process.

Book excerpt: The report describes an investigation made in order to determine the validity of the classical model for the detonation structure of condensed phase explosives in view of recent contradictory evidence, determine any effect of the complex wave interactions of the reflected shock and rarefaction waves within the reaction zone on the measured free surface velocities of the shocked metal, an effect which has previously been neglected, and remove the anomaly of the 'decay' zone.

Book excerpt: General properties of Zeldovich-von Neumann-Doering (Z-N-D) waves are derived with an arbitrary equation of state. Constant velocity one-dimensional cylindrically and spherically symmetric detonations are shown to propagate as unsteady-state waves; exact integral relationships for steady-state axial flow in a cylindrical charge are obtained as generalized Rankine-Hugoniot equations without approximating divergence terms. More specific properties of steady-state Z-N-D waves are based on the polytropic equation of state of detonation products. Properties of steady-state reaction zones are derived with the equations for axial flow. With respect to a one-dimensional Chapman-Jouguet (C-J) wave, flow divergence produces an increase in the ratio of sound speed to particle velocity at the sonic point, and a corresponding decrease in the ratio of C-J density to initial density. A point of inflection in the particle velocity-distance profile of a C-J wave is associated with a temperature dependent energy release rate. Inverse methods are developed for constructing exact solutions for Z-N-D waves in terms of hydrodynamic properties that completely determine the flow field. Solutions for decaying, accelerating, and oscillatory one-dimensional waves are constructed to examine the dependence of detonation on equation of state, rear boundary conditions, and energy release rate. A solution for axial flow in a two-dimensional detonation is constructed to demonstrate the influence of radial flow divergence on reaction zone as charge diameter increases from its critical value to infinity.

Available in PDF, EPUB and Kindle. Book excerpt: It is known that the Chapman-Jouguet theory of detonation is based on the assumption of an instantaneous and complete transformation of explosives into detonation products in the wave front. Therefore, one should not expect from the theory any interpretations of the detonation limits, such as shock initiation of det onation and kinetic instability and propagation (failure diameter). The Zeldovich-Von Neuman-Doring (ZND) theory of detonation appeared, in fact, as a response to the need for a theory capable of interpreting such limits, and the ZND detonation theory gave qualitative interpretations to the detonation limits. These interpretations were based essentially on the theoretical notion that the mechanism of explosives transformation at detonation is a combustion of a layer of finite thickness of shock-compressed explosive behind the wave shock front with the velocity of the front. However, some experimental findings turned out to be inconsistent with the the ory. A very small change of homogeneous (liquid) explosives detonation velocity with explosive charge diameter near the rather sizable failure diameter is one of the findings. The elucidation of the nature of this finding has led to the discovery of a new phenomenon. This phenomenon has come to be known as the breakdown (BD) of the explosive self-ignition behind the front of shock waves under the effect of rarefaction waves.
