Sediment loads transfer in hydraulic installations and their consequences for the O&M of modern canal systems is emerging as one of the most important considerations in hydraulic engineering projects apriticularly those which are inteded to feed the irrigation and draiange schemes of large command areas such as the Dez and Mogahn in Iran.. The aim of this paper is to investigate the applicabili...

This paper describes the passive flow control of fluid in the downstream direction of the circular tube and in tube banks by means of splitter plate. Heat transfer and pressure drop depend on complex flow pattern of fluid in tube banks, whereas pressure drop linked directly with the fluid pumping capacity. A primary focus is to review experimental, analytical and numerical works that had been c...

In this paper, high order LES has been conducted for investigation on the flow around micro vortex generator (MVG) at Mach number 2.5 and Reθ=5760. The mechanism of vortex ring generation behind MVG, especially in the initial stage of the ring generation has been studied in detail. The results show that the ring structures come from both the sheer layer on the upper boundary of momentum deficit...

introduction: erythrocyte sedimentation rate (esr) remains as one of the most reliable tests in clinical practices. yet its use is time consuming and requires a large blood sample. the aim of this study was assessing a faster and reliable method of esr estimation. methods: an esr estimation method was described and performed on 108 patients using capillary tube (micro esr) and capillary periphe...

In this paper performance characteristics for a Ranque-Hilsch vortex tube are presented. The was of divergent design and optimised both size performance, to be used supply cold air turbomachinery experiments with feed in the pressure range 3.0–7.0 bar, overall mass flow rates 0.05–0.14 kg/s. Optimum fixed parameters selected from literature were: ratio cold-exit diameter inlet internal (0.50); ...

AC-driven electrothermal flow is used to enhance the chaotic mixing through vortex flow in micro-fluidic systems by nearly an order of magnitude. Diffusion of heat and momentum can be increased because of the electrothermal force acting on the fluid through the applied AC electric field. Numerical simulation of vortex-assisted mixing in circular microchannel flow is investigated by solving a se...
