circular- crested weirs are employed for flow measurement among their other wide applications in hydraulic engineering. they can also be used to control water level in farm ponds and reservoirs. advantages of the circular crested weirs as compared to other weirs include the stable overflow pattern, the simplicity of design and their associated lower costs. in this study, the curvilinear flow pa...

Background: Epididymal sperm has been recovered with the aim of conserving potentially valuable genetics Materialss from post mortem males for subsequent usage in assisted reproduction technologies. Among the quality parameters of spermatozoa, motility and velocity patterns are sensitive for chemical and physical components of medium which they were diluted. Also close correlation between sperm...

This paper describes the recently developed mixed mimetic spectral element method for the Stokes problem in the vorticity-velocity-pressure formulation. This compatible discretization method relies on the construction of a conforming discrete Hodge decomposition, that is based on a bounded projection operator that commutes with the exterior derivative. The projection operator is the composition...

A new numerical method for solving the twodimensional, steady, incompressible, viscous flow equations on a Curvilinear staggered grid is presented in this paper. The proposed methodology is finite difference based, but essentially takes advantage of the best features of two well-established numerical formulations, the finite difference and finite volume methods. Some weaknesses of the finite di...

In this paper we apply the recently developed mimetic discretization method [44] to the mixed formulation of the Stokes problem in terms of the vorticity-velocity-pressure formulation. The mimetic discretization presented in this paper and in [44] is a higher-order method for curvilinear quadrilaterals. It relies on the language of differential k-forms, k-cochains as its discrete counterpart, a...

Drought is a major constraint for agricultural production worldwide and likely to become aggravated by global warming. It can induce land degradation, exorbitant food prices menace livelihoods. Approaches retaining optimal yield, especially in rainfed staple crops such as cowpea [Vigna unguiculata (L.) Walp] are paramount. Biostimulants vermicompost leachate (VCL), seaweed extract [Kelpak® (KEL...

Currently, nanotechnology and nanoparticles have been quickly emerged gained the attention of scientists due to their massive applications in environmental sectors. Nanotechnology also encompasses ability design, characterize, manufacture, implement nano-sized structures. Today, metal oxide stand out industrial various fields applied nanotechnology. Among nanoparticles, iron (FeO-NPs) are one w...

Membraneless microseparation by asymmetric inertial migration is studied in curvilinear laminar flows and evidence of the microseparation is presented. Along a curvilinear laminar flow, transverse particle migration involves competition between three shear-flow effects; the tubular pinch effect, centrifugal force, and Dean's vortex. Equilibrating control of migration allows for particle separat...
