Prediction Design Method on Whole Working Process Co-Simulation of Torpedo Thermal Propulsion System

In view of lack of a multi-disciplinary integrated design environment for torpedo thermal propulsion system and inability to achieve interdisciplinary cross-system coordination, this paper investigates the co-simulation prediction design method on the whole working process of torpedo thermal propulsion system based on the development status of torpedo thermal propulsion system simulation. This study provides a simulation and verification system of the thermal propulsion system using different dimensions, different professional simulation software and test data, and explores the prediction design method of the subsystem numerical simulation, scheme design optimization and the system numerical tests, in realizing the drive of the design parameters and interdisciplinary cross-system simulation, completes the digital verification and performance evaluation. The simulation examples show that the method enables the visual display of fluid field details and parameter changes, thereby facilitating the virtual validation of system performance. Using this method, the transfer from the conventional design to predicted design is achieved. As a result, design success rate and product reliability are enhanced while the design period is reduced, which is crucial for the research and development of torpedo thermal propulsion systems.
