标题： PoroTwin: A digital twin for a FluidFlower rig

摘要： 我们提出了一种框架，用于使用数字孪生技术集成实验和模拟非均质多孔介质中的示踪剂传输。在我们的设置中，物理资产是一个米级流体花装置。数字孪生包括一个基于传统物理的前向模拟工具和一种校正技术，该技术可以补偿模拟结果与观测之间的差异。后者扩展了基于物理的模拟范围，并允许我们在定量意义上弥合模拟与实验之间的差距。我们描述了物理和数字孪生的设置，包括使用云技术的数据传输协议。数字孪生的准确性在一个高扩散的人工案例中得到证明，这必须通过校正方法以及在地质复杂介质中的模拟来补偿。然后，数字孪生被应用于通过操控实验装置中的流体注入和生产来控制示踪剂传输，从而实现物理和数字孪生之间的双向耦合。 显示英文摘要

摘要： We present a framework for integrated experiments and simulations of tracer transport in heterogeneous porous media using digital twin technology. The physical asset in our setup is a meter-scale FluidFlower rig. The digital twin consists of a traditional physics-based forward simulation tool and a correction technique which compensates for mismatches between simulation results and observations. The latter augments the range of the physics-based simulation and allows us to bridge the gap between simulation and experiments in a quantitative sense. We describe the setup of the physical and digital twin, including data transfer protocols using cloud technology. The accuracy of the digital twin is demonstrated on a case with artificially high diffusion that must be compensated by the correction approach, as well as by simulations in geologically complex media. The digital twin is then applied to control tracer transport by manipulating fluid injection and production in the experimental rig, thereby enabling two-way coupling between the physical and digital twins.
