This paper presents a numerical investigation of the laminar mixed convection flow of a radiating gas in an inclined lid-driven cavity. The fluid is treated as a gray, absorbing, emitting, and scattering medium. The governing differential equations including continuity, momentum and energy are solved numerically by the computational fluid dynamics techniques (CFD) to obtain the velocity and tem...

In this study, the numerical investigation of Al 2 O 3 -Water nanofluid mixed convection in a T-shaped lid-driven cavity presence thermal barrier with positioning at different positions is investigated by two-phase mixture model. Variable parameters study are aspect ratio (AR), volume fraction nanoparticles ( ? ), Richardson numbers (Ri), and placements cavity. The results indicated that increa...

The dynamics of a fully three-dimensional lid-driven cubical cavity (3D-LDC) flow at several post-critical conditions, i.e., beyond the first bifurcation, are elucidated using both linear and nonlinear analyses. When Reynolds number is increased critical value, symmetry breaks down intermittently with subsequent gradual growth in spanwise inhomogeneity. This results crossflow as well pronounced...

Pharmacological dopamine (DA) replacement with Levodopa [L-dihydroxyphenylalanine (L-DOPA)] is the gold standard treatment of Parkinson's disease (PD). However, long-term L-DOPA treatment is complicated by eventual debilitating abnormal involuntary movements termed L-DOPA-induced dyskinesia (LID), a clinically significant obstacle for the majority of patients who rely on L-DOPA to alleviate PD-...

Introduction: A low iodine diet (LID) is recommended prior to the Radioactive Iodine-131 (RAI) treatment or scanning in differentiated thyroid carcinoma (DTC) post total thyroidectomy. However, recommended strictness of LID is varying among major guidelines. This study was aim to investigate the patient’s compliance to LID by measuring the urinary iodine level post LID. <...

Nutrient absorption in the small intestine cannot occur until molecules are presented to the epithelial cells that line intestinal villi, finger-like protrusions under enteric control. Using a two-dimensional multiscale lattice Boltzmann model of a lid-driven cavity flow with 'villi' at the lower surface, we analyse the hypothesis that muscle-induced oscillatory motions of the villi generate a ...
