Abstract
Flow characteristics of air guides of an air jet loom have been experimentally investigated. We compare the flow in air guides with the flow jetted free in atmosphere to clarify the effects of air guides.
The main results are as follows:
(1) A flow field in air guides can be classified into two regions.
(2) The first region is found at the up-stream part of guides and the distribution of the axial velocity along guides shows very similar features to a free jet flow.
(3) The other region is at the down-stream part. The axial velocity slightly decreases along guides and the distribution of radial velocity can be expressed by the power law of about 1/6.
