Abstract

A method for determining a flow behavior of a medium uses at least one analysis device placed inside the medium. The at least one analysis device is freely moveable in the medium and supplies data characterizing at least one property of the medium flow behavior to a data evaluation device. The at least one property of the medium flow behavior is determined by the data evaluation device on the basis of the data in selected areas or in all areas through which the at least one analysis device flows with the medium.

First claim

What is claimed is:

1. A method for determining a flow behavior of a medium, comprising:
placing at least one analysis device inside the medium, with the at least one analysis device being freely moveable in the medium;
supplying data characterizing at least one property of the medium flow behavior from the at least one analysis device to a data evaluation device;
determining with the data evaluation device the at least one property of the medium flow behavior, in a flow area through which the at least one analysis device flows with the medium, based on the supplied data characterizing the at least one property of the medium flow behavior.

2. The method of claim 1 , and further comprising providing the at least one analysis device with a locating unit by a position of the at least one analysis device inside the medium is determined and evaluated by the data evaluation device to determine at least one property of the medium flow behavior.

3. The method of claim 1 , and further comprising providing the at least one analysis device with at least one memory unit in which the characterizing data is stored and which, at a later time, is evaluated by the data evaluation device to determine the at least one property of the medium flow behavior.

4. The method of claim 1 , and further comprising providing the at least one analysis device with a transmitter unit by which the characterizing data is transmitted to a receiver device and evaluated by the data evaluation device to determine the at least one property of the medium flow behavior.

5. The method of claim 1 , and further comprising forming the at least one analysis device to substantially imitate a shape and size of particles forming the medium.

6. The method of claim 1 , and further comprising setting a time interval between times when the characterizing data is selected depending on a movement velocity of the medium.

7. The method of claim 1 , and further comprising using a result from the data evaluation device for setting a parameter of the method.

8. The method of claim 1 , wherein the characterizing data relates to at least one chosen from a position of the at least one analysis device, a movement of the at least one analysis device, a rotation of the at least one analysis device, an acceleration of the at least one analysis device, a pressure in an area of the at least one analysis device, and a temperature in the area of the at least one analysis device.

9. The method of claim 8 , and further comprising using at least one sensor of the at least one analysis device to determine the at least one chosen from the position of the at least one analysis device, the movement of the at least one analysis device, the rotation of the at least one analysis device, the acceleration of the at least one analysis device, the temperature in the area of the at least one analysis device, and the pressure in the area of the at least one analysis device.

10. The method of claim 1 , and further comprising providing the medium for surface treatment of components including at least one chosen from vibratory grinding, plunge grinding and ball polishing.

11. The method of claim 10 , and further comprising providing the at least one analysis device with a locating unit by a position of the at least one analysis device inside the medium is determined and evaluated by the data evaluation device to determine at least one property of the medium flow behavior.

12. The method of claim 11 , and further comprising providing the at least one analysis device with at least one memory unit in which the characterizing data is stored and which, at a later time, is evaluated by the data evaluation device to determine the at least one property of the medium flow behavior.

13. The method of claim 12 , and further comprising providing the at least one analysis device with a transmitter unit by which the characterizing data is transmitted to a receiver device and evaluated by the data evaluation device to determine the at least one property of the medium flow behavior.

14. The method of claim 13 , wherein the characterizing data relates to at least one chosen from a position of the at least one analysis device, a movement of the at least one analysis device, a rotation of the at least one analysis device, an acceleration of the at least one analysis device, a pressure in an area of the at least one analysis device, and a temperature in the area of the at least one analysis device.

15. The method of claim 14 , and further comprising using at least one sensor of the at least one analysis device to determine the at least one chosen from the position of the at least one analysis device, the movement of the at least one analysis device, the rotation of the at least one analysis device, the acceleration of the at least one analysis device, the temperature in the area of the at least one analysis device, and the pressure in the area of the at least one analysis device.

16. The method of claim 15 , and further comprising providing the at least one analysis device with a plurality of sensors.

17. The method of claim 16 , and further comprising forming the at least one analysis device to substantially imitate a shape and size of particles forming the medium.

18. The method of claim 17 , and further comprising setting a time interval between times when the characterizing data is selected depending on a movement velocity of the medium.

19. The method of claim 18 , and further comprising placing several analysis devices inside the medium.

20. The method of claim 19 , and further comprising using a result from the data evaluation device for setting a parameter of the method.
