Detailed Description

A class for calculating the time development of the gas composition from the gas velocity.

This class implements "batch tracking", which is a method for calculating the time development of the gas composition. This is done by setting up "batches" of gas with a given composition, and advancing each batch according to the gas velocity around each batch.

The batch tracking procedure is documented in Gas composition tracking in transient pipeline flow (Chaczykowski et. al., Journal of Natural Gas Science and Engineering 2018).

Member Function Documentation

advect() [1/2]

static BatchTrackingState BatchTracking::advect ( const BatchTrackingState &  state, const arma::uword  dt, const arma::mat &  inletAndOutletConcentration, const arma::vec &  velocity  )

static

Calculate new Batch positions from gas velocity.

This is the main advection function, which performs the calculations (all other advect functions are just wrappers around this one).

Advection is performed by translating each Batch according to the velocity of the gas around each Batch.

The batch tracking procedure is documented in Gas composition tracking in transient pipeline flow (Chaczykowski et. al., Journal of Natural Gas Science and Engineering 2018).

Parameters

state	The current state, the positions and concentrations of all batches.
dt	Time step [s].
inletAndOutletConcentration	Inlet and outlet concentration as column vectors.
velocity	The velocity in the pipeline.

Returns

A copy of state with updated batch positions.

advect() [2/2]

static BatchTrackingState BatchTracking::advect ( const BatchTrackingState &  state, const arma::uword  dt, const Pipeline &  pipeline, const BoundaryConditions &  boundaryConditions  )

static

A wrapper around BatchTracking::advect(const BatchTrackingState&, const double, const arma::mat&, const arma::vec&)

See also

BatchTracking::advect(const BatchTrackingState&, const double, const arma::mat&, const arma::vec&)

Parameters

dt	Time step [s].
state	BatchTrackingState to advect
pipeline	Instance of Pipeline containing the current Pipeline state. Will get velocity from this.
boundaryConditions	Boundary conditions.

Returns

A copy of state with updated batch positions.
