Large-eddy simulation (NEK5000) of an idealized, subsurface single-phase oil-gas plume

A turbulence resolving simulation of a near-field plume is conducted using a nonhydrostatic Navier-Stokes solver (NEK5000). The computation is conducted using a 17th order spatial discretization for numerical accuracy and on about 900 cores of a recent Cray XE6m. The single-phase plume is driven by momentum and buoyancy anomalies at the inlet. Once the plume reaches a steady state through open upper boundary conditions, an injection of a passive tracer is carried out to explore possible mixing characteristics of dispersants. This dataset was created by the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE).本研究采用非静力学纳维-斯托克斯（Navier-Stokes）求解器（NEK5000）开展近场羽流的湍流解析模拟。计算采用17阶空间离散格式以保障数值精度，并在最新款Cray XE6m超级计算机的约900个计算核心上完成。该单相羽流由入口处的动量与浮力异常驱动。当羽流通过开放上边界条件达到稳态后，研究团队注入被动示踪剂以探究分散剂的潜在混合特性。本数据集由环境碳氢化合物输运高级研究联盟（Consortium for Advanced Research on Transport of Hydrocarbon in the Environment, CARTHE）创制。
