We consider the dynamic polaron model of hydrated electron state on basis a system three nonlinear partial differential equations with appropriate initial and boundary conditions. A parallel numerical algorithm for solution this has been developed. Its effectiveness tested few multi-processor systems. simulation states formation in water under action ultraviolet range laser irradiation performed. The results are shown to be reasonable agreement experimental data theoretical predictions.

In this work, a numerical study of the solutions parabolic and hyperbolic equations heat conduction with same physical parameters is carried out comparative analysis results obtained out. The mathematical formulation problem discussed. action laser taken into account through source function, which was chosen as double femtosecond pulse. equation, in contrast to one, there an additional parameter that characterizes relaxation time flux. addition, equation contains term - derivative power...
Numerical simulation of the photoexcited electron states formation in water under action ultraviolet range laser irradiation is carried out on basis polaron model with a time-dependent calculation hydrated absorption band width. This framework shown to reproduce well experimental data light by polarized water. Effectiveness parallel implementation tested HybriLIT cluster.
In this paper, we report a numerical simulation of laser ablation material by ultrashort pulses. The thermal mechanism is described in terms one-dimensional nonstationary heat conduction equation coordinate system associated with moving evaporation front. action taken into account through the functions source conductivity that determine and time dependence source. For given dose irradiation sample, profiles sample temperature at different times, dynamics displacement boundary due to...
