Experiments were conducted to investigate local heat transfer coefficients and flow characteristics of air flow in a 962 lm inner diameter stainless steel microtube (minichannel). The effects of heat loss, axial heat conduction and viscous heating were systematically analyzed. Heat losses during the experiments with gas flow in small diameter tubes vary considerably along the flow length, causi...

In this paper, the fully-developed temperature profile and corresponding Nusselt value is determined analytically for a gaseous flow in a microtube with a thermal boundary condition of constant wall heat flux. The flow assumed to be laminar, and hydrodynamically and thermally fully developed. The fluid is assumed to be constant property and incompressible. The effect of rarefaction, viscous dis...

Traditional aqueous self-assembly of tubular structures (as well as other aggregates) usually relies on the hydrophobic effect, a relatively weak and nondirectional interaction. The resultant aggregates are inherently soft, fluid, and less-ordered. Alternatively, we report a novel kind of nonamphiphilic selfassembly of microtubes in aqueous solutions of cyclodextrin/ionic surfactant (CD/IS) com...

Western blot (5) is a powerful tool to study the regulation of specific proteins from cell cultures or tissue extracts. The standardization of the total protein content is an essential step before the analysis of specific proteins regulated by different factors in cells or tissues. Standard protein assay procedures (1,4) based on the colorimetric reactions are often affected by the concentratio...

Micro-Tube Plasmas (?TP) have been gaining attention for applications ranging from medicine to material science and analytical chemistry due their small size, low cost of operation flexibility. In the present work a specific ?TP, known as Flexible Micro Tube Plasma (F?TP) is investigated experimentally and, first time, numerically well. The creation, propagation mechanisms properties ionization...

    Given the need to increase the efficiency of heat transfer in thermal systems, especially systems using nanofluids in microscale and nanoscale heat transfer equipment ideas to improve their performance is very good.In present study, the flow and heat transfer of Water-Cu nanofluid in micro-tube with slip regime with constant wall heat flux numerically simulated with low Reynolds numbers.
