Abstract: Aiming at the problems of the single collaboration mode and the high cost of building a collabora-tion environment of the existing flow field collaboration analysis application,according to the requirements of flow field collaboration analysis,an immersive virtual reality collaboration framework for flow field visualization is proposed.Firstly,the collaboration message that supports flow field collaboration synchro-nization is defined.Then a collaborative pipeline tree is proposed that supports the sharing of flow field visualization results.Finally the demonstration collaboration analysis mode and free collaboration analysis mode of immersive virtual reality flow field visualization collaborative analysis are designed and imple-mented.Users can choose the appropriate collaboration analysis mode according to the actual task,to sup-port the team in the flow field collaboration analysis.By building a prototype system and performing a demonstration collaboration analysis and a free collaboration analysis on the flow field data respectively,from the perspective of observation of different users,the collaboration process of the two collaborative analysis modes is demonstrated.
