    Numerical simulation of MHD Sakiadis flows of convectively heated thixotropic nanofluids in a porous medium using revised transport laws and Wakif-Buongiorno's model by A. Wakif

    Published 2025-03-01
    “…Due to the particular inability of Fourier's and Fick's laws in the realistic quantification of transfer processes that can occur certainly within a flowing biphasic mixture, on the one hand, and the explanation of the memory relaxation features of such a non-homogenous medium, on the other hand, the present scrutinization intends to propose a representative biphasic flow model to reveal the principal demeanors of convectively heated thixotropic nanofluids during their steady two-dimensional flows in the laminar regime over a stretching planar geometry in a Darcy-Forchheimer porous medium under the magnetic impact of an external electromagnetic device. For this purpose, the renovated formulation of Wakif-Buongiorno's model is linked theoretically with the constructive equation of the thixotropic model and the generalized transport laws to describe properly the nanofluid motion, the thermal energy balance, and the nanoparticles’ molar concentration distribution under the assumptions of the boundary layer concept and the passive nanoparticles’ control approach. …”

    Investigation of Strong Strata Behaviors in the Close-Distance Multiseam Coal Pillar Mining by Hongwei Mu, Yongsheng Bao, Dazhao Song, Dongfang Su

    Published 2021-01-01
    “…Moreover, a theoretical model for the mechanism of strong strata behaviors in the close-distance multiseam coal pillar mining was established, which was validated by the monitoring data of seismic computed tomography CT, microseism, and electromagnetic radiation (EMR). Furthermore, the results of the study indicated that the main factors affecting the strong strata behaviors were the static stress concentration caused by the overlying coal pillars and the dynamic disturbance caused by the fracturing and slipping of the overlying coal pillars and roof under the influence of mining. …”
