The effects of sheet thickness on the oscillation of an air-blasted liquid sheet
In the present work, experiments have been performed to study the influence of the sheet thickness on the oscillatory movement of an air-blasted liquid sheet, based on measurements of oscillation frequencies and wavelengths. To measure the wavelengths, a novel double-beam diffraction technique has been implemented. It has been determined that the sheet oscillation frequency depends on the inverse of the square root of the sheet thickness, while the wavelength increases linearly as sheet thickness is increased. Based on these dependencies, suitable non-dimensional groups are proposed to describe the problem. Wave propagation velocities have also been calculated and discussed.
The present invention provides a touch screen suitable for use in high definition CRT in recent years, FPD and other display screens and other anti-Newton ring sheets used and the use of the anti-Newton ring sheet touchscreen. Anti-Newton ring sheet of the present invention is a plurality of column 2 by spacing structure 3 formed in parallel, the column height 2 is configured to vary the flow direction of the ridgeline. 2 changes the height of the column is preferable that the structure is periodic variation period which is within the range of 20μm ~ 4000μm.
