Abstract
  • An experimental and analytical study of negatively buoyant jets discharged vertically upward into a crossflow current was conducted to obtain information on the fate of oil well produced water. This information could be used to validate and calibrate the short and intermediate term portions of a computer model used to predict the disposal. The experimental results include the dilution arid plume width, measured at selected incremental distances downstream of the discharge. Independent parameters varied in this investigation were the discharge densimetric Froude Number, and the ambient to discharge velocity ratio. Results indicate that the Froude Number has the greatest effect on dilution; decreasing the Froude Number increases both dilution and plume width. Altering the velocity ratio has little effect on dilution, but does affect plume width. The analytical portion of this study includes a brief presentation of the background of plume modeling, the mathematical development of the produced water computer model, and an outline of the procedure for tuning the coefficents within the model using the experimental results of this investigation. It is expected that the results presented here are sufficient for validating and calibrating the initial phases of the computer model. Upon calibration and validation, the model can be used as a predictive tool for determining the fate of negatively buoyant jets.
