A three-dimensional fluid velocity simulation method and device

Abstract

The invention discloses a three-dimensional fluid velocity simulating method and device. The device is characterized in that a linear motor rotor is controlled to carry out inclined linear movement ina plane, a dip angle is formed between the plane and the horizontal plane, an inclined linear movement track is obtained, the movement speed of the linear motor rotor can be broken up into a horizontal speed and a vertical speed, an ocean current velocity detector which is fixedly arranged on the linear motor rotor can acquire the corresponding horizontal speed and the corresponding vertical speed along with linear movement of the linear motor rotor, the ocean current velocity detector which moves is immersed below the liquid level of measured liquid, and thus, horizontal flow and upward flowof ocean current can be simulated. A linear motor carries out inclined linear movement, thus, the ocean current velocity detector can simultaneously obtain the corresponding horizontal speed and thecorresponding vertical speed in the measured liquid, and simulated test on the horizontal flow and the upward flow of an ocean is realized in an experimental environment.

Description

technical field [0001] The invention relates to ocean current velocity measurement and current velocity simulation equipment. Background technique [0002] Ocean current velocity is an important indicator of seawater monitoring. The ocean has both horizontal and vertical upwelling and downwelling. Upwelling is a very important phenomenon although the flow rate is small. A large amount of seawater nutrients in the deep water area are brought to the surface with the upwelling, providing rich bait for fish farming; the cold water brought by the upwelling can better cool the heat generated by the nuclear power plant units. The velocity difference between the horizontal current and the upwelling current is very large. How to simultaneously simulate the horizontal current and the upwelling of the ocean under the experimental environment has become a research hotspot. [0003] At present, there is no good solution on how to simultaneously simulate horizontal flow and upwelling wi...

Problems solved by technology

[0003] At present, there is still no good solution on how to simultaneously simulate horizontal flow and upwelling with large speed differences under experimental conditions. The current simulation devices in the prior art are only biased towards one of the flow velocities
