Background: Fasciola hepatica is a genus of the trematodes which mainly affects the liver of sheep and these livestock are accidentally infected by eating plants or drinking water contaminated with the metacercariae of this parasite. These parasites can cause considerable economic damage by destroying the liver and bile ducts. OBJECTIVES: The aim of this study was to evaluate the role of ultras...

Microchannels are well known in microfluidic applications for the control and separation of microdroplets cells. Often objects flow experience inertial effects, resulting dynamics that is a departure from underlying channel dynamics. This paper considers small neutrally buoyant spherical particles suspended through curved duct having square cross-section. The particle experiences combination li...

An improved Metal Solar Wall (MSW) with integrated thermal energy storage is presented in this research. The proposed MSW makes use of two, combined, enhanced heat transfer methods. One the methods characterized by filling tested ducts a commercially available copper Wired Inserts (WI), while other one uses dimpled or sinusoidal shaped duct walls instead plane walls. Ducts having square semi-ci...

The performance of an explicit algebraic stress model is assessed in predicting the turbulent ow and forced heat transfer in straight ducts, with square, rectangular, trapezoidal and triangular cross sections, under fully developed conditions over a range of Reynolds numbers. Iso-thermal conditions are imposed on the duct walls, and the turbulent heat uxes are modeled by gradient-di usion type ...

The Galerkin weighted residuals method is extended solve the laminar, fully developed flow and heat transfer of Al2O3-water nanofluid inside polygonal ducts with round corners for the constant heat flux and uniform wall temperature boundary conditions. Using the method, semi-analytical, closed-form solutions are obtained for the friction coefficient and the Nusselt number in terms of the radius...
