Abstract A two-dimensional numerical simulation is performed in the present work to study the structure of a detonation wave in high activation energy mixtures, which are characterized by their turbulent reaction zone structure and unreacted pockets. The process of transverse wave and triple point collision with the channel walls, formation and consumption mechanism of unburnt gas pockets is e...

 Propagation of Electromagnetic wave in a plasma in the equilibrium state can cause instability. Investigating the situations in which this kind of instability occurs and grows is an important issue. In this paper, Raman instability in plasma is analyzed by particle simulation method. In terms of physical investigation, plasma is a very complicated environment and experimentally too expensive. ...

Investigation of the waves generated by underwater disturbances gives precious insight into the effect of man-made underwater explosions as well as natural phenomena, such as underwater volcanoes or oceanic meteor impact. On the other hand, prediction of the effects of such waves on the coastal installations and structures is required for preparation worthwhile criteria for coastal engineers to...

Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies.  Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes.  In this paper, the results of numerically simulate...

This theoretical study examines the characteristics of a surface wave driven plasma monopole antenna using finite difference time domain method (FDTD) as well as commercial full wave simulator. The results show that the full wave simulator can be considered as an acceptable tool in simulation of a plasma antenna. Input impedance, radiation pattern, gain, efficiency and radar cross section of pl...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...

Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...

The significant effect of waves on coastal and marine activities urges the precise identification of wave characteristics using field measurements, theoretical studies, physical modeling or numerical simulations. In order to study thoroughly the wave climate in the Caspian Sea, a wave modeling and hindcast project was performed by Iranian National Center for Oceanography. In this study, one of ...
