Abstract

Abstract

At present, the Monte Carlo simulation of the wake bubble curtain is mostly used to simulate the photon scattering direction, and few scholars have studied the distribution of photon transmission time. In this paper, based on the volume scattering function of Henyey-Greestein, a forward scattering model of pulsed laser in water was established. The propagation process of photons in bubble curtain was simulated by the Monte Carlo method based on this model, and the distribution of transmission time of photons in water containing bubble curtain was obtained. The model was used to simulate the photon transmission time under different bubble curtain thicknesses, bubble sizes, and detection distances. The simulation results show that greater thickness of the bubble curtain indicates longer photon transmission time in the bubble curtain and greater backward movement of the pulsed laser, which is manifested as a broader and wider pulsed laser. A larger bubble size represents a greater scattering degree of the laser by the bubble and greater backward movement of the pulsed laser. As the distance between the laser light source and the bubble curtain becomes larger, the photon transmission time is shifted backward, and the pulse width and peak intensity change slightly. According to the start-stop time of photons detected by the detector and the peak change of photon number, the characteristics of wake can be reflected, thus realizing the accurate positioning, identification, and measurement of wake.
