Study of GLR and Inlet Velocity on Hydrocyclone for Fracturing Flow‐Back Fluids

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
In this work, based on the Reynolds stress model (RSM) of the computational fluid dynamics (CFD) software Fluent and experimental method, the velocity field, pressure characteristics, split ratio, and separation efficiency of the hydrocyclone are analyzed under different gas‐liquid ratios (GLRs).

Effect of Calcined Hard Kaolin Dosage on the Strength Development of CPB of Fine Tailings with Sulphide

Advances in Materials Science and Engineering, Volume 2017, Issue 1, 2017., 2017
This study presents the effect of calcined hard kaolin (CHK) as replacement (15–50 wt.%) to Portland cement (PC) on the strength development of cemented paste backfill (CPB) of fine tailings containing sulphide. PC is used as binder at 20 wt.% dosage. The results show that CPB sample containing 30 wt.% CHK replacements produces the desired strength and
