Development and Application of a Percolation Velocity Monitoring Method in Multiphase Percolation Physical Experiments
Table 1
Common detection methods of seepage velocity.
| Method | Advantage | Limitations/disadvantages |
| Electrical detection [4ā6] | Widely applicable conditions | The mechanism of action is unclear, and the resolution is low | Electromagnetic detection [7, 8] | Quick and intuitive | There are too many influencing factors to quantitatively describe | Elastic wave method [9, 10] | Intuitive monitoring methods | Not significantly effective for small-scale detection | Tracer method [11] | Ability to monitor the leakage channel and determine the leakage speed | Radioactivity and contamination of tracers | Temperature change [11] | High testing accuracy, which can reflect changes in flow velocity | The respective velocity of multiphase flow cannot be reflected |
