Problems solved by technology
[0004] However, the problem with related technologies is that since the acquisition of the random flow structure is based on large sample measurements and a large amount of data screening, if there are too many invalid data, it will consume a lot of experimental equipment resources, and the experimental efficiency is low

The invention discloses a fluid measurement method and device and a storage medium. The method comprises the following steps of: obtaining a speed signal and / or a pressure signal through a detection device disposed at the upstream of a flow field; judging whether the speed signal and / or the pressure signal meet / meets a preset condition or not; and under the condition that the speed signal and / or the pressure signal meet / meets the preset condition, controlling an acquisition device arranged at the downstream of the flow field to work so as to acquire image information of the flow field. Therefore, the fluid measurement method provided by the embodiment of the invention is simple; through the detection device arranged at the upstream of the flow field and the acquisition device arranged at the downstream of the flow field, when the speed signal and / or the pressure signal meets the preset condition, the image information of the flow field can be acquired; and the active measurement and capture of the fluid are realized; and therefore, the fluid measurement efficiency is improved, and meanwhile, the resource consumption of experimental equipment is reduced.
Description
technical field [0001] The present invention relates to the technical field of fluid measurement, in particular to a fluid measurement method, a fluid measurement device and a computer-readable storage medium. Background technique [0002] At present, some random flow structures will appear intermittently in some special flow fields, such as turbulent spots, stripes, etc. For example, "throwing up" and "sweeping down" events will occur randomly in the near-wall region of the turbulent boundary layer. Studying the characteristics of these randomly occurring flow structures is important for understanding the physical laws of transition and turbulent boundary layer. meaning. [0003] In related technologies, the following methods are usually used to capture the random flow structure, for example, after a long period of large-sample measurement, a large amount of data is screened to obtain the random flow structure. [0004] However, the problem with related technologies is th...
