FLUID MECHANICAL PROPERTY MEASUREMENT METHOD AND MEASUREMENT DEVICE |
| 摘要 |
An object is to measure a mechanical property of a fluid at a temporal resolution of at least 100 [μs]. Therefore, a method comprising: causing a droplet 21 to fly by ejecting a fluid to be measured from a nozzle 11a as the droplet 21; generating an electric field in a space around a flight path 22 of the droplet 21 by applying a voltage to an electrode arranged in the vicinity of the flight path 22; deforming the droplet 21 in a way of contactless deformation with a dielectric force induced by the electric field; and measuring a mechanical property of the fluid based on temporal variation of deformation state of the droplet 21 after deforming the droplet 21. |

1. A fluid mechanical property measurement method, the method comprising:
causing a droplet to fly by ejecting a fluid to be measured from a nozzle as the droplet; generating an electric field in a space around a flight path of the droplet by applying a voltage to an electrode arranged in the vicinity of the flight path; deforming the droplet in a way of contactless deformation with a dielectric force induced by the electric field; and measuring a mechanical property of the fluid based on temporal variation of deformation state of the droplet after deforming the droplet. |
