The focus of the second workshop was directed towards the development, analysis, and application of basic models in high speed propulsion of particular interest to NASA. The exploration of a dual approach combining asymptotic and numerical methods for the analysis of the models was particularly encouraged. The objectives of this workshop were i) the genesis of models that would capture or reflect the basic pllysical phenomena in SCRAMJETs and/or oblique detonation-wave engines (ODWE), and ii) the stimulation of a greater interaction between NASA experimental research community and the academic community.The lead paper by D. Bushnell on the status and issues of high speed propulsion relevant to both the SCRAMJET and the ODWE parallels his keynote address which set the stage of the workshop. Following the lead paper were five technical sessions with titles and chairs: Experiments (C. Rogers), Reacting Free Shear Layers (C. E. Grosch), Detonations (A. K. Kapila), Ignition and Structure (J. Buckmaster), and Unsteady Behaviour ('1'. L. Jackson).The session chairs were responsible for the planning of their session. In each of the sessions formal discussion papers were given by experts followed by a general discussion involving the participants. This volume contains the manuscripts presented in each session. In addition, a panel discussion was held on the last day, chaired by J. Buckmaster. The panel members were

“…Only in recent years had investigation revealed the existence of stable spherical detonation waves (3)(4)(5)(6)(7)(8), and this work has been limited by the methodological difficulties involved; i.e., large volumes of gas are necessary for even a short path for the detonation wave in a spherical container. These studies indicated that in spherical detonation stronger initiation is generally required and detonation limits are reduced.…”

“…The propagation mechanism of a diverging detonation wave remains a subject of research in the detonation theory. Theoretical studies of diverging cylindrical and spherical detonation and its steady solution originate in the pioneer works of Jouguet [1], Courant and Friedrich [2], Taylor [3], Manson and Ferrie [4], and Lee et al [5]. Assuming a steady C-J detonation where the product flow is isentropic if no further chemical reactions, frictions and heat losses are considered, the basic isentropic equations can be expressed by …”

a b s t r a c t Self-organized generation of transverse waves associated with the transverse wave instabilities at a diverging cylindrical detonation front was numerically studied by solving two-dimensional Euler equations implemented with an improved two-step chemical kinetic model. After solution validation, four mechanisms of the transverse wave generation were identified from numerical simulations, and referred to as the concave front focusing, the kinked front evolution, the wrinkled front evolution and the transverse wave merging, respectively. The propagation of the cylindrical detonation is maintained by the growth of the transverse waves that match the rate of increase in surface area of the detonation front to asymptotically approach a constant average number of transverse waves per unit length along the circumference of the detonation front. This cell bifurcation phenomenon of cellular detonations is discussed in detail to gain better understanding on detonation physics.
