Design And Implementation Of Hypersonic Boundary Layer Transition Data Management System

The problem of transition is the "Century problem" left by classical mechanics.Boundary layer transition problems involved four types of experiments: wind tunnel experiments,flight experiments,calculation example experiments,and stability analysis experiments,etc.Any one of these experiments requires a professional team to conduct the transition problem research which need coordinated by many teams.However,the exchange of experimental data between various teams is very inconvenient,which greatly affects the research efficiency of transition problems.This paper combines the four types of experiments involved in transition issues.From the perspective of software engineering,using Python + My SQL + Nginx + Docker as the main technical means,we design and develop a set of data management system,related to transition issues for wind tunnel,flight,calculation,stability analysis and other four types of experiments.The main work of this paper is the problems faced by the actual combination of conventional data management system and transition problem research data which included: 1.How to retrieve key experimental data from massive transition data;2.Flow field data for wind tunnel experiments which contains more than 320,000 pieces of data,how to quickly visualize it to users;3.The transition data management system will be deployed in multiple local area networks,how to ensure the high portability of the system.While researching the key issues of the fusion of conventional data management system and transition data,this paper also implements a set of transition data management system,including wind tunnel experiments,flight experiments,calculation example experiments and stability analysis experiment's parameter input and experiment result entry function,fast retrieval function of massive experiment data,visualization function of experiment result file,deletion function of experiment data and result file.The system has an access control function,which implements permission control on users to prevent data loss and leakage.The test results show that the transition data management system has reached the design target.
