环形水槽物理模拟的沉积学应用与发展趋势
Progress and Prospects in the Sedimentological Applications of a Circular Flume Physical Simulation
摘要
Abstract
[Significance]Physical simulation experimentation in a circular flume is an effective means of simulating the sedimentary process and revealing its formation mechanism.It is of great significance to research directions such as hydraulic engineering,environmental science,sedimentology,and hydrocarbon exploration.The circular flume sustains continuous fluid flow under the influence of inertial and shear forces,and is considered to approximate the transport and deposition of sediment over an infinitely long distance.Therefore,it approximately reproduces aspects of transport distance and fluid velocity that occur in environmental fluid flow,breaking through the application limita-tions of traditional flume simulations.[Progress]To meet the research needs of different application scenarios,circu-lar flumes have gradually evolved into four types:conventional circular flumes,in situ circular flumes,mini circular flumes,and racetrack flumes.To date,physical simulations using circular flumes have achieved fruitful results in studying depositional characteristics,bedform morphology,and depositional mechanisms,among other aspects.How-ever,there is still a relative scarcity of research in sedimentary physical simulation.With the development of tech-nology and equipment,research in sedimentary physical simulation has also made significant progress.For example,gravity flow deposition,the dynamics of fine-grained deposition transport,and tidal and wave deposition have become important research areas in physical simulations using circular flumes.It is recognized that there are several limitations in circular flume physical simulations,such as the influence of secondary circulation and the tracking of lateral deposition evolution,which will be optimized in subsequent research through improved experimental designs and enhanced measurement accuracy.[Conclusions and Prospects]In summary,systematically expanding the applicability of physical simulation with annular flumes based on sedimentology principles will contribute to the innovative development of basic sedimentological theories and many aspects such as fine-grained sedimentology and unconventional hydrocarbon sedimentology.关键词
