Numerical simulation of the interaction of laser light with dispersed particles at different temper-atures of the surface layer of the oceans and seas. We were obtained shape and amplitude of the acoustic signal formed during this interaction and assess the pressure amplitudes of the acoustic signals at different temperatures of the surface layer of the liquid. The evaluation of the ampli-tude of the acoustic pressure has built its dependence on the surface temperature of the liquid.

Waves Interaction

The model of the electromagnetic waves interaction with small particles and clusters is proposed in the case when the dielectric permittivity of the material depends both on the electric and magnetic fields. We consider the class of the differential equations solutions that is obtained in the framework of the model and allows take into account the geometric structure of the small dispersed particles or clusters. The motion and precipitation of water clusters in narrow tubes is investigated by molecular dynamics methods.

The primary goal of this paper is to seek solutions to the coupled nonlinear partial differential equations (CNPDEs) by the use of q-homotopy analysis transform method (q-HATM). The CNPDEs considered are the coupled nonlinear Schrödinger–Korteweg–de Vries (CNLS-KdV) and the coupled nonlinear Maccari (CNLM) systems. As a basis for explaining the interactive wave propagation of electromagnetic waves in plasma physics, Langmuir waves and dust-acoustic waves, the CNLS-KdV model has emerged as a model for defining various types of wave phenomena in mathematical physics, and so forth. The CNLM model is a nonlinear system that explains the dynamics of isolated waves, restricted in a small part of space, in several fields like nonlinear optics, hydrodynamic and plasma physics. We construct the solutions (bright soliton) of these models through q-HATM and present the numerical simulation in form of plots and tables. The solutions obtained by the suggested approach are provided in a refined converging series. The outcomes confirm that the proposed solutions procedure is highly methodological, accurate and easy to study CNPDEs.

Tube Geometry

In this study, transverse and longitudinal accelerations of a full caliber-shell shot by a medium-caliber gun were measured directly during the internal ballistic (IB) phase. The data were transmitted outside the tube by modulation of LASER light emission and recoded into acceleration values. The results were analyzed through the numerical simulation of the response of the tube traversed by the projectile and with the internal-ballistic data providing the longitudinal projectile acceleration. The analysis reveals that the in-bore projectile movements are both influenced by the tube geometry (curvature and straightness defects) and by the tube response during the internal ballistic phase. However, in this work, the tube response appeared to be of greater influence on the projectile dynamics than the tube initial static geometry. Results provide basis for further calibration studies.
