The present article focuses on the evaluation of a first-moment closure model applicable to film cooling flow and heat transfer computations. The present first-moment closure model consists of a higher level of turbulent heat flux modeling in which two additional transport equations for temperature variance kθ and its dissipation rate εθ are ...

In this study conditions of refinement of car wash effluent from Paniz station in omidiyeh, Khuzestan by microfiltration polyvinylidene fluoride (PVDF- MFB) membrane with pore size 0.13 micrometer by taguchi method was investigated. Taguchi method has been applied to investigate the effect of various operating parameters such as feed pressure at 3 levels (0.4, 0.7 and 1.00 bars), feed Flow rate...

INTRODUCTION. Hyperparathyroidism is a common finding in patients with renal insufficiency and parathyroid hormone (PTH) is considered a uremic toxin responsible for many of the abnormalities of the uremic state and bone disease. The aim of this study was to investigate the influence of permeability of low-flux versus high-flux dialysis membranes on intact PTH during hemodialysis in children. M...
