Carbo-jet汽油 德国
2009/12/4
本文对Carbo-jet 汽油气化装置功能的一个主要方面,即当空气量变化时,汽油量能随之而变,但空燃比却保持不变的机理作了详细分析,并探讨了孔板旋转曲面的特性方程。
Air Drag Force on a Yarn and Use of a Coaxial Jet for Yarn Operation
Yarn operation Air drag force Coaxial circular jet Coaxial annular jet Power-saving
2009/5/5
we calculated numerically compressible airflows past a yarn in a thin pipe in order to operate yarn using both a circular jet and an annular jet. We proposed the way to arrange air drag coefficients o...
Numerical Study on the Principle of Yarn Formation in Murata Air-Jet Spinning
Swirling airflow Fibers Nozzle Yarn MJS
2009/4/21
A realizable k-ε turbulence model was adopted to study the airflow characteristics inside the two nozzles including the slotting-tube of Murata air-jet spinning (MJS). Actions of the two nozzles and ...
Mathematical Modeling of Pneumatic Melt Spinning of Isotactic Polypropylene. Part. I. Modeling of the Air Jet Dynamics
fiber spinning melt blowing nonwoven computational fluid dynamics turbulence
2009/2/19
In this series of publications, the process of nonwoven melt blowing of ultra-fine fibers is presented. The process starts in the dual slot die where two converging air jets draw the molten polymer st...
Selected Aspects of Yarn Formation with a False-twist Method in the Air-jet Spinning Chamber
air-jet spinning false-twist chamber yarn formation
2009/2/16
Some selected aspects of the yarn formation in the air-jet false-twist spinning chamber operating according to the MJS (Murata Jet Spinning) principle were discussed. The chamber under investigation i...
Air Flow in the Air-jet False-twist Spinning Chamber
air-jet spinning false-twist chamber air flow
2009/2/13
We discuss the air flow in a false-twist spinning chamber operating according to the MJS (Murata Jet Spinning) principle. The chamber under investigation is characterised by a straight inlet channel a...

In this work, a collection of decorative textiles for home furnishing was designed on a CAD CAM system, printed with an ink-jet printer, and transferred into production using rotary screen printing. T...
Investigation of Electrospinning with the Use of a Multi-Jet Electrospinning Head
electrospinning multi-jet electrospinning nanofibres nanofibrous mat
2009/2/9
Three types of multi-jet electrospinning heads, series, elliptic and concentric, were constructed in compact forms. Their usefulness for electrospinning was tested with the use of poly(vinyl alcohol) ...
Velocity Control of Weft Insertion on Air Jet Looms by Fuzzy Logic
