Description

one

The invention relates to devices for determining the dependence of the magnitude of blunt refraction from speed radiumites: due to the shift of the optical current and active and can be used in scientific laboratories of institutes and precursors where the movement of liquid flows is studied. Pharynx and he n o-op t and h her to and m method.

In known devices of similar purpose, onticeok active fluid is placed in the annular gap between two sections. Coaxial mi cyles: h1drams, one of iKOTOpblX

In the case of rotation of the inner cylinder, the gradient of the nearness of D and our shear depth r has 1 maximals. “I1 and mip-on the surface of the ziutren) of its cylinder. The heterogeneity of the gradient sex field is determined by oDiomeiK-ie.M

devices. The presence of inhomogeneity is very complicated; it naturally complicates the processing of experimental results and is a drawback of these devices.

In the proposed device, these drawbacks are eliminated due to the simultaneous rotation of the disks located on the common oc: i rotation with the same angular velocity

In the BiiejuiHe.M disk Normally: two holes were made to the axis of rotation, with a thread to fill the gap with the liquid under study, which are fixed with screws 11, and the end part of the screws is made flush with the inner walls of disk 8, so that it does not makes changes in the notes when the fluid moves. One of the screws is hollow, and in; it is placed the numbers of the thermonar 12 with a slide.

On the tubular stand, fasten the ring water intake 13 with a socket / eight type BQO | M 14. rack, IB. Cutout. Nozzles 15 with connecting pipe 16 are placed.

The STANDARD is already equipped with a polar-ontic system consisting of 1 source 17, (Polarizer 18, analyzer 19, mirror 20, and recording device 21. The beam coming from the light source is precisely diaphragm- ed by means of the gap.

The device works as follows. The disks are driven in B: by a rotor with an electric launcher, the number of which rotates the plate varies in a wide range. Change the number of revolutions, ie, measure the magnitude of zoimoto refraction of 4 / g at different velocity gradients or shear stresses -. For nosodderzhanny (constant temperature in the gap with the test liquid thermostating liquid is supplied from the thermostat through the connecting pipe 16, into the nozzle 15, and from them to the inner wall of the rotating disk 4). and returns to the thermostat again.
