The application discloses a kind of underwater bottom sealing concrete pouring flow state evolution simulation method, system and storage medium, method includes: collection underwater bottom sealing area three-dimensional space data and anti-dispersion concrete initial rheological parameter, builds three-dimensional fluid calculation domain model.Rely on rheological parameter to establish water-concrete two-phase flow evolution model, embedding rheological parameter time-varying correction function that can reflect the underwater loss of anti-dispersion component.Combining conduit layout form and flow control scheme sets dynamic inlet boundary, obtains phase interface, velocity field, concentration field and other flow state data by model numerical operation.Rely on simulation data to extract concrete diffusion, anti-dispersion distribution characteristics, determine pouring blind area and segregation risk area, according to this to prepare conduit flow collaborative optimization control instruction.Provide reliable technical support for improving bottom sealing concrete forming quality.

A method comprising a conductive fluid flowing through a conduit made of a non-magnetic material, a flow meter located on or near the conduit, and a magnetic field source spaced from the conduit that produces a first magnetic field interacting at least partially with the conductive fluid flowing through the conduit, includes generating sensor data representative of the strength of a second magnetic field that interacts at least partially with the flow meter. The second magnetic field is produced by eddy currents induced in the conductive fluid by the first magnetic field. Based on processing the generated sensor data representative of the strength of the second magnetic field, the method includes determining a flow rate of the conductive fluid through the conduit.

The invention discloses a fixed positive and negative pressure conduit flow testing method. According to the invention, through the cooperation of accurate parameter setting and a staged pressure regulation strategy, the pressure control performance is obviously improved. The set target pressure value and the test duration serve as the core basis of adjustment, and the adjustment direction of the pressure system completely meets the test requirement; according to the staged strategy, the initial pressure difference is shortened through the maximum capacity of hardware, then the fluctuation range is compressed through multiple rounds of fine calibration, the single logic limitation of conventional closed-loop control is broken through, and it is ensured that the pressure is stabilized within extremely high precision. The dynamic pre-stabilization mode not only shortens the pressure establishment time, but also provides a stable environmental basis for formal testing, directly improves the accuracy of flow measurement, enables the result to reflect the real performance of the conduit better, adapts to the quick response of different pressure requirements, reduces unnecessary waiting time, and improves the overall testing efficiency.
