CFD simulation of nanofluids flow dynamics including mass transfer

Development of a Partitioning Kinetic Model of Biomass Gasification in Supercritical Water with a Fluidized Bed Reactor

“…Supercritical water gasification fluidized bed reactor (SCWFB), put forward by our laboratory, has potential for the commercial application of this technology because heat and mass transfer are enhanced in this reactor, and the biomass could be gasified efficiently, which could avoid the plugging problem that occurred in a traditional continuous tubular reactor easily. Because in a tubular reactor, the particles may be deposed on the wall, which was not beneficial to the heat and mass transfer, and reduced the gasification efficiency. , Thus, research studies on gasification in the SCWFB reactor were widely conducted, both by experiment and simulation, focused on gasification performance, , flow structure, − and reactor design. − The simulation method was more widely used , because the extreme operating condition limited the measuring method, making it difficult to obtain the experimental information on the flow field distribution, temperature distribution, and so forth. Therefore, improving the accuracy of the reactor simulation has become relatively significant, among which developing an accurate kinetic model of biomass is essential because it is essential for designing, evaluating, and improving of the reactor.…”
