AB  - High-pressure rotary jetting (HPRJ) remediation is a recent-applied technology 
      for in situ remediation of contaminated soils. The effectiveness of remediation 
      depends upon the migration and distribution of the injected agents in the soil. 
      However, the corresponding migration mechanisms have received little attention. 
      In this study, laboratory HPRJ tests and numerical simulations were performed 
      using chlorine (Cl(-)) as a tracer to investigate the transport during HPRJ and 
      the subsequent advection and diffusion. The test results showed that the HPRJ 
      transported Cl(-) into the mixing zone by eroding the sand, and the radius of the 
      mixing zone could be reasonably predicted by the erosion model. The Cl(-) 
      concentration decreased linearly along the radial direction in the mixing zone. 
      In addition, the Cl(-) transport distance increased with the increase in nozzle 
      diameter, jetting times, especially injection pressure, and decreased with an 
      increasing rotation speed. The Cl(-) concentration and radial uniformity were 
      correlated positively with rotation speed, particularly nozzle diameter and 
      jetting times. Numerical simulation showed that part of Cl(-) migrated from the 
      mixing zone to diffusion zone by advection-diffusion after rotary jetting, which 
      contributed positively to the agent distribution distance and uniformity. The 
      Cl(-) migration was dominated by advection in the initial stage (30 days), while 
      diffusion became more important thereafter.
