Class DistillationColumnMatrixSolver

java.lang.Object
neqsim.process.equipment.distillation.DistillationColumnMatrixSolver
public class DistillationColumnMatrixSolver extends Object
A matrix-based solver for DistillationColumn using the Inside-Out algorithm approach. This solver uses a tridiagonal matrix algorithm (TDMA) to solve component material balances.

    • solveComponentBalances

      private double[][] solveComponentBalances()
      Solves the tridiagonal matrix for each component to find liquid molar flow rates. Returns x[tray][component] (liquid mole fractions) or l[tray][component] (molar flows). Let's return molar flows l[tray][component].
      Returns:
      liquid molar flow rates as l[tray][component]
