Numerical Simulation on Hydrofracture Propagation in Fractured-Vuggy Unconventional Reservoirs by Tingxue Jiang, Haitao Wang, Xiaobing Bian, Daobing Wang, Jun Zhou, Bo Yu

“…Acid fracturing of carbonate reservoir is completed through the complex mechanical mechanism of interaction between vug and hydraulic fracture (HF). We use the equivalent method of reducing the rock strength by acid etching and serious fluid leakoff during interaction of HF and vug to establish a finite element (FE) model of HF propagation during acid fracturing in the fractured-vuggy carbonate reservoir. …”

Comparative Study on the Field- and Lab-Based Soil-Water Characteristic Curves for Expansive Soils by Bakht Zamin, Hassan Nasir, Muhammad Ali Sikandar, Waqas Ahmad, Beenish Jehan Khan, Mahmood Ahmad, Muhammad Tariq Bashir

“…Therefore, it is crucial to assess them as unsaturated soil, and the soil-water characteristic curve (SWCC) is an essential tool for measuring unsaturated soils’ mechanical and hydraulic properties. The main objective of this study was to establish both field- and lab-based SWCCs for the expansive soils and compare them for determining the possible difference between them. …”

A New Coupled CFD/Neutron Kinetics System for High Fidelity Simulations of LWR Core Phenomena: Proof of Concept by Jorge Pérez Mañes, Victor Hugo Sánchez Espinoza, Sergio Chiva, Robert Stieglitz

“…By applying codes like CFD (computational fluid dynamics) and SP3 (simplified transport) reactor dynamics it is possible to describe the underlying phenomena in a more accurate manner than by the nodal/coarse 1D thermal hydraulic coupled codes. By coupling the transport (SP3) based neutron kinetics (NK) code DYN3D with NEPTUNE-CFD, within a parallel MPI-environment, the NHESDYN platform is created. …”
