Abstract:
It is believed that there are two aspects of possible progresses crucial to give rise to a revolutionary changes in chemical engineering: one is physical understanding of mesoscale phenomena at different levels of chemical processes; another is computational capability with sufficient predictability and scalability. Combining these two progresses, the long dream of chemical engineers to realize real-time simulation of chemical processes, that is, virtual reality, could become a real practice. This was just a dream 10 years ago, but now would be probably a reality if sufficient efforts could be made along with this direction.

This presentation reviews the relevant progresses on these two aspects at Institute of Process Engineering, Chinese Academy of Sciences. It is indicated that there are huge potentials in integrating mesoscale understanding and computational capability to realize virtual reality in chemical engineering. Understanding mesoscale phenomena will gives rise not only to good predictability in physical modeling, but also to complete optimization of efficiency of computation, vice versa, computation will be an important tool in understanding mesoscale complexity which is likely not feasible for most of measurement technologies due to the limitation of resolution in both time and space. A demonstration version of virtual reality of gas-solid two-phase systems, based on this mesoscale strategy, will be presented. Challenges in next step of development will be identified. As long as virtual reality becomes a real practice, the capability of chemical engineering will be totally revolutionized! However, traditional thinking mode is not sufficient to lead to this change, and transdisciplinarity is the only path to reach this goal!
