Future prospects of rotor spinning
Labour productivity has been continuously increasing since the days of spinningjenny to the modern day roto r frames. To visualize the spinning industry in the year 2000, the past and the present technologica l changes have been analyzed so as to assess their overall impact in terms of labour complement.. material handling, required operative skill and automation. The automation in textile indu...
متن کاملPIV measurements of an air jet impinging on an open rotor-stator system
The current work experimentally investigates the flow characteristics of an air jet impinging on an open rotor-stator system with a low non-dimensional spacing, G = 0.02, and with a very low aspect ratio, e/D = 0.25. The rotational Reynolds numbers varied from 0.33 × 10 to 5.32 × 10, while the jet Reynolds numbers ranged from 17.2×10 to 43×10. Particle image velocimetry (PIV) measurements were ...
متن کاملNusselt Number Measurement of Air Flow between Grooved Rotor and Stator of a Generator
In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

متن کاملAn Open-Air School
At first children sent here for treatment were mainly from the poorest homes. This is no longer so. The boys and girls, selected as the result of medical inspection from all the schools in Bradford?including secondary schools?are representative of every artisan class. No child is admitted here with any sort of infectious disease. Most suffer from ansemia and the ills that follow in its train. E...
