Turbulence Rheometer 2

The main working mechanism in the device is a piston hydraulic separator; hydraulic fluid drives a piston, which imparts movement to the liquid being tested. Thus, contact between the liquid sample and the hydraulic fluid is not possible.

The sample is pumped through a small diameter test capillary. The effectiveness of ATP is determined either by direct pressure measurement or by calculating the change in the pressure drop gradient at different sections of the capillary. In this way, samples with different Reynolds numbers and at different flow rates can be examined. By comparing the pressure drop when using ATP and without using them, conclusions are drawn about the effect of ATP on the test fluid and the effectiveness of ATP. By varying the flow rate, different Reynolds numbers can be obtained during one test. Cyclic, repeated testing allows the long-term stability of ATP to be verified.

To ensure maximum accuracy of measurement results, the test bench does not have sudden changes in diameter in the measuring pipeline. The special geometry of the piston and its head ensures constant acceleration during injection and minimizes shear forces. The measuring capillary, sample cylinder and sample container are completely thermostatic. Depending on the viscosity of the sample, capillaries of different lengths and different diameters can be used.
