On “jamitons,” self-sustained nonlinear traffic waves
Phantom jams,” traffic blockages that arise without apparent cause, have long frustrated transportation scientists. Herein, we draw a novel homology between phantom jams and a related class of self-sustained transonic waves, namely detonations. Through this analogy, we describe the jam structure; favorable agreement with reported measurements from congested highways is observed. Complementary n...
متن کاملTheoretical Analysis on Deflagration-to-Detonation Transition
The study on deflagration-to-detonation transition (DDT) is very important because this mechanism has relevance to safety issues in industries, where combustible premixed gases are in general use. However, the quantitative prediction of DDT is one of the major unsolved problems in combustion and detonation theory to date. In this paper, the DDT process is studied theoretically and the critical ...
متن کاملEffect of Porous Thrust Surfaces on Detonation Transition and Detonation Tube Impulse
As pulse detonation engine development matures, it becomes increasingly important to consider how practical details such as the implementation of valves and nozzles will affect performance. Inlet valve timing and valveless inlet designs may result in flow of products back upstream and, consequently, reduction in impulse over the ideal case. Although proper inlet design or operation under flowin...
متن کاملA Review on Detonation Gun Sprayed Coatings
Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant ...
متن کاملInvestigations on Deflagration to Detonation Transition
4 simplified model that can predict the transition from compaction to detonation and shock to detonation is given with the uim of describing experiments in beds of porous HMX. In the case of compaction to detonation. the energy of early impact generates a slowly moving. convectivereactive deflagration that expands near the piston face and evolves in a manner that is characteristic of confined d...
