Enclosing class:
FlowRateOptimizer
public static class FlowRateOptimizer.ProcessCapacityTable extends Object implements Serializable
Represents a 2D capacity table showing maximum flow rates at different pressure boundary conditions.

This table maps inlet/outlet pressure combinations to maximum achievable flow rates while respecting equipment constraints. It is the inverse of the lift curve representation - instead of "flow vs outlet pressure at fixed inlet pressure", it shows "max flow for each pressure combination".

This format is particularly useful for reservoir simulators where pressures are known from deliverability curves and the question is "what flow rate can the production system handle?"

    • getOperatingPoint

      public FlowRateOptimizer.ProcessOperatingPoint getOperatingPoint(int inletIndex, int outletIndex)
      Gets the operating point for a specific inlet/outlet pressure combination.
      Parameters:
      inletIndex - index into inlet pressures array
      outletIndex - index into outlet pressures array
      Returns:
      the operating point, or null if infeasible

    • getFlowRateValues

      public double[][] getFlowRateValues()
      Extracts maximum flow rates as a 2D array.
      Returns:
      2D array [inletPressures][outletPressures] of flow rates

    • getTotalPowerValues

      public double[][] getTotalPowerValues()
      Extracts total power values as a 2D array.
      Returns:
      2D array [inletPressures][outletPressures] of total power (kW)

    • getMaxUtilizationValues

      public double[][] getMaxUtilizationValues()
      Extracts maximum utilization values as a 2D array.
      Returns:
      2D array [inletPressures][outletPressures] of max utilization

    • findMaxFlowRatePoint

      public FlowRateOptimizer.ProcessOperatingPoint findMaxFlowRatePoint()
      Finds the operating point with maximum flow rate.
      Returns:
      the operating point with highest flow rate, or null if empty

    • findMinimumPowerPoint

      public FlowRateOptimizer.ProcessOperatingPoint findMinimumPowerPoint()
      Finds the operating point with minimum total power.
      Returns:
      the operating point with lowest total power, or null if empty
