Two-Point control method
In this method two control points are designated in the 1D domain, and the value of the temperature at these points is fixed. The values of the control points are imposed and thus serve as a boundary condition that affects the solution of the governing equations in the 1D domain. The imposition of fixed points in the domain means that the original set of governing equations' boundary conditions would over-determine the problem. Thus, the boundary conditions are changed to reflect the fact that the control points are serving as internal boundary conditions. The imposition of the two internal boundary conditions requires that two other boundary conditions be changed. The first is the boundary condition for the continuity equation at the left boundary, which is changed to be a value that is derived from the solution at the left boundary. The second is the continuity boundary condition at the right boundary, which is also determined from the flow solution by using the oxidizer axial velocity equation variable to compute the mass flux at the right boundary. This method is based on the work of Nishioka et al. [32] .

In such cases, the parameters may be set in method _finalize. This method is called just before the Newton solver is called, and the x array is guaranteed to be the local solution vector for this domain that will be used as the initial guess. If no such parameters need to be set, then method _finalize does not need to be overloaded.

◆ eval()

void eval	(	size_t	jGlobal,

overridevirtual

Evaluate the residual functions for axisymmetric stagnation flow.

If jGlobal == npos, the residual function is evaluated at all grid points. Otherwise, the residual function is only evaluated at grid points j-1, j, and j+1. This option is used to efficiently evaluate the Jacobian numerically.

These residuals at all the boundary grid points are evaluated using a default boundary condition that may be modified by a boundary object that is attached to the domain. The boundary object connected will modify these equations by subtracting the boundary object's values for V, T, mdot, etc. As a result, these residual equations will force the solution variables to the values of the connected boundary object.

Parameters

	jGlobal	Global grid point at which to update the residual
[in]	xGlobal	Global state vector
[out]	rsdGlobal	Global residual vector
[out]	diagGlobal	Global boolean mask indicating whether each solution component has a time derivative (1) or not (0).
[in]	rdt	Reciprocal of the timestep (`rdt=0` implies steady-state.)

Computes the radiative heat loss vector over points jmin to jmax and stores the data in the qdotRadiation variable.

The simple radiation model used was established by Liu and Rogg [23]. This model considers the radiation of CO2 and H2O.

This model uses the optically thin limit and the gray-gas approximation to simply calculate a volume specified heat flux out of the Planck absorption coefficients, the boundary emissivities and the temperature. Polynomial lines calculate the species Planck coefficients for H2O and CO2. The data for the lines are taken from the RADCAL program [9]. The coefficients for the polynomials are taken from TNF Workshop material.

	)

protectedvirtual

Evaluate the continuity equation residual.

This function calculates the residual of the continuity equation

\[ \frac{d(\rho u)}{dz} + 2\rho V = 0 \]

Axisymmetric flame: The continuity equation propagates information from right-to-left. The \( \rho u \) at point 0 is dependent on \( \rho u \) at point 1, but not on \( \dot{m} \) from the inlet.

Freely-propagating flame: The continuity equation propagates information away from a fixed temperature point that is set in the domain.

Unstrained flame: A specified mass flux; the main example being burner-stabilized flames.

The default boundary condition for the continuity equation is ( \( u = 0 \)) at the left and right boundary.

Parameters

[in]	x	Local domain state vector, includes variables like temperature, density, etc.
[out]	rsd	Local domain residual vector that stores the continuity equation residuals.
[out]	diag	Local domain diagonal matrix that controls whether an entry has a time-derivative (used by the solver).
[in]	rdt	Reciprocal of the timestep.
[in]	jmin	The index for the starting point in the local domain grid.
[in]	jmax	The index for the ending point in the local domain grid.

		double *	rsd,
		int *	diag,

protectedvirtual

Evaluate the momentum equation residual.

The function calculates the radial momentum equation defined as

\[ \rho u \frac{dV}{dz} + \rho V^2 = \frac{d}{dz}\left( \mu \frac{dV}{dz} \right) - \Lambda \]

The radial momentum equation is used for axisymmetric flows, and incorporates terms for time and spatial variations of radial velocity ( \( V \)). The default boundary condition is zero radial velocity ( \( V \)) at the left and right boundary.

	)

protectedvirtual

Evaluate the lambda equation residual.

The function calculates the lambda equation as

\[ \frac{d\Lambda}{dz} = 0 \]

The lambda equation serves as an eigenvalue that allows the momentum equation and continuity equations to be simultaneously satisfied in axisymmetric flows. The lambda equation propagates information from left-to-right. The default boundary condition is \( \Lambda = 0 \) at the left and zero flux at the right boundary.

For argument explanation, see evalContinuity().

		double *	rsd,
		int *	diag,

	)

protectedvirtual

Evaluate the energy equation residual.

The function calculates the energy equation:

\[ \rho c_p u \frac{dT}{dz} = \frac{d}{dz}\left( \lambda \frac{dT}{dz} \right) - \sum_k h_kW_k\dot{\omega}_k - \sum_k j_k \frac{dh_k}{dz} \]

The energy equation includes contributions from chemical reactions and diffusion. Default is zero temperature ( \( T \)) at the left and right boundaries. These boundary values are updated by the specific boundary object connected to the domain.

For argument explanation, see evalContinuity().

protectedvirtual

Evaluate the species equations' residuals.

The function calculates the species equations as

\[ \rho u \frac{dY_k}{dz} + \frac{dj_k}{dz} = W_k\dot{\omega}_k \]

The species equations include terms for temporal and spatial variations of species mass fractions ( \( Y_k \)). The default boundary condition is zero flux for species at the left and right boundary.

Evaluate the electric field equation residual to be zero everywhere.

The electric field equation is implemented in the IonFlow class. The default boundary condition is zero electric field ( \( E \)) at the boundary, and \( E \) is zero within the domain.

protectedvirtual

Evaluate the oxidizer axial velocity equation residual.

The function calculates the oxidizer axial velocity equation as

\[ \frac{dU_{o}}{dz} = 0 \]

This equation serves as a dummy equation that is used only in the context of two-point flame control, and serves as the way for two interior control points to be specified while maintaining block tridiagonal structure. The default boundary condition is \( U_o = 0 \) at the right and zero flux at the left boundary.
