In order to measure flow rate in open channels, including irrigation hydraulic structures are used with a relatively high degree of reliance. Venturi flumes among the most common and efficient type, they can discharge using only water level at specific point within converging section an empirical relationship. There have been limited number attempts simulate venturi flume computational fluid dy...

Due to rising human infertility, sperm motility has been an important subject. Among the hundreds of millions sperms on journey up oviducts, only a few excellent travelers will reach eggs. This is affected by many factors, some which include quality, density, fluid rheology and chemotaxis. In addition, swimming through different body tracks fluids involves complex flagellar, environment, multi-...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...
