If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...
This study investigates the origin and sustenance of self induced oscillations shock structures in a hypersonic flow over double wedge configuration. Previously, various researchers have considered configuration for inviscid with variations different inflows as well geometric parameters such inflow Mach number , angles, lengths. Few recently published articles reveal an unsteady physics involve...
let g be a graph with p vertices and q edges and a = {0, 1, 2, . . . , [q/2]}. a vertex labeling f : v (g) → a induces an edge labeling f∗ defined by f∗(uv) = f(u) + f(v) for all edges uv. for a ∈ a, let vf (a) be the number of vertices v with f(v) = a. a graph g is said to be vertex equitable if there exists a vertex labeling f such that for all a and b in a, |vf (a) − vf (b)| ≤ 1 and the in...
BACKGROUND Milk ejection is essential for a successful lactation, however techniques to measure milk ejection in women are often complex and invasive. Recent research has demonstrated that at milk ejection, milk duct diameter increased in the breast (measured by ultrasound) at the same time as milk flow rate increased (measured using a weigh balance). This study aimed to evaluate a purpose-buil...
objective: in this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. methods: the base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. lorentz electric force, which is used as stimulating flow factor, is created by appl...
The present study aims to investigate the of double-diffusive convection on peristaltic flow under assumption long wavelength and low Reynolds number. mathematical modelling for a two-dimensional flow, along with double diffusion in nanofluids is considered. motivation research work analyze effects thermal radiation through porous medium nonuniform channel. heat flux linear approximation employ...
از این روی، 56 دانشجوی رشته ی مترجمی زبان انگلیسی دانشگاه کاشان در این تحقیق شرکت نموده و سه متن از نوع توضیحی نیستند و همچنین هیچ رابطه معناداری بین flow و پیشینه ی یادگیری فراگیران وچود ندارد. در بخش کیفی مطالعه، با 4 نفر از فراگیران که از میان جمعیت اماری فاز اول مطالعه انتخاب شده بودند مصاحبه گردید که اطلاعات به دست آمده در این قسمت، یافته های آماری را تأئید می کند. کلید واژگان: flow، نو...
Serial femtosecond crystallography requires reliable and efficient delivery of fresh crystals across the beam of an X-ray free-electron laser over the course of an experiment. We introduce a double-flow focusing nozzle to meet this challenge, with significantly reduced sample consumption, while improving jet stability over previous generations of nozzles. We demonstrate its use to determine the...
Folding transformations on processor arrays result in smaller processor arrays, more efficient work for the processing elements, a decrease in I/O time and pipelineable implementations. The regular folding procedure is realized to improve the efficiency of processor arrays whilst retaining the complexity of the data communications, the processor operations and the regular data flow. The efficie...
