Abstract

Abstract

To explore the development characteristics of gas jets generated by pulsed detonation hydroramjet working underwater in open-ended water guides, numerical simulations and experimental validations were conducted on underwater detonation gas jets within a cylindrical confined space by utilizing the detonation of combustible gases to generate pulsating bubbles. A flow model of a single gas jet in a confined space was established based on the Reynolds-averaged Navier-Stokes equations, the K-epsilon two-equation model, and the Volume of Fluid (VOF) interface tracking method coupled with the advection equation. The CompressibleInterFoam solver in OpenFOAM was employed for numerical simulations of pulsed detonation gas jets in confined spaces. The results showed that the amplitude of the leading shock wave in the confined space changed insignificantly compared to free underwater space. However, the pressure disturbance caused by the gas jet significantly increased, and its duration prolonged. Additionally, it led to a noticeable increase in pressure within the confined space compared to outside the confined space. The pulsation period of gas bubbles in the confined space extended to approximately 60 ms, and the radial dimension of the confined space had little effect on the fluctuation period of the gas bubbles. It can be seen that confined space can increase the near field pressure at the outlet of the underwater detonation tube and extend the action time of the gas jet. The research results have important guiding significance for the study of thrust performance improvement methods for pulse detonation hydroramjet.
