Segregated Fluid Energy Models Reference

There are three Segregated Fluid Energy models, which are companion models to the Segregated Flow model: the Segregated Fluid Enthalpy, Segregated Fluid Temperature, and Segregated Fluid Isothermal models.

The Segregated Fluid Enthalpy model solves the total energy equation Eqn. (1658) with chemical thermal enthalpy as the solved variable. Temperature is then computed from enthalpy according to the equation of state. This model is recommended for any simulation involving combustion. It is required with the flamelet combustion models.

The Segregated Fluid Temperature model solves the total energy equation Eqn. (1658) with temperature as the solved variable. Enthalpy is then computed from temperature according to the equation of state. This model is appropriate for simulations that do not involve combustion.

The Segregated Fluid Isothermal model keeps the temperature in the continuum constant. For problems where the temperature variations are small and negligible, it would be computationally expensive to solve an ordinary energy transport equation when it would yield a nearly constant field of temperature. Hence, Simcenter STAR-CCM+ includes the isothermal energy option to provide a constant temperature field for all models that require temperature.

Segregated Fluid Energy Models Properties

Continuum Temperature
Specifies the temperature of the continuum.
Convection
Sets the discretization scheme that Simcenter STAR-CCM+ uses for computing the convection flux on a cell face in appropriate transport equations. More information is given in the related topic for the Convection Term:
  • 1st-Order: First-order upwind scheme. This scheme scales the transported quantity by the upstream or downstream mass flowrate depending on flow direction. Only use when a higher-order scheme fails to give convergence, or in order to obtain an initial solution before switching to a higher-order scheme.
  • 2nd-Order: Second-order upwind scheme. This scheme introduces linear interpolation of cell values on either side of the upstream or downstream face. Using this scheme can lead to poorer convergence properties, but gives accuracy as good as or better than the first-order scheme.
  • MUSCL 3rd-order/CD: Hybrid MUSCL third-order/central-differencing. Adds the Bounded Differencing sub-node.
Flow Boundary Diffusion
When activated, this property includes the flow-boundary diffusion fluxes (or viscous fluxes for flow models) as given by Eqn. (899). This property is activated by default.
Secondary Gradients
There are two sources of secondary gradients in Simcenter STAR-CCM+ flow solvers:
  • boundary secondary gradients for diffusion
  • interior secondary gradients for diffusion at cell faces

Use this property to control which gradients are included in the solver. On gives both gradients while Off excludes them. Interior Only and Boundaries Only select the corresponding gradients.

Upwind Blending Factor

The default provides the most robustness for the scheme. Reducing it would, in principle, increase accuracy. However, unless you are thoroughly familiar with the theoretical aspects of bounded differencing, do not change this property. The default value reflects optimization for accuracy and performance.

If this occurs, a message is printed to the Output window.

Wall
Circumferential Averaging of Energy
When On, activates averaging of the heat flux between a boundary and its region with relative rotation between them—for example, a stationary boundary and a fluid in a rotating region. See Energy Averaging for Rotating Fluids with Stationary Wall Boundaries. The default is Off.

This option becomes available only when the tangential velocity of the wall boundary is different from the angular velocity of the fluid region. This velocity difference can be achieved by one of the following:

  • The wall boundary is associated with a reference frame different from the Region Reference Frame and the rotation vector (= rotation axis x rotation rate) between the two reference frames is different. The fluid region can rotate by defining a moving reference frame. For more information, see Reference Frames.
  • The wall boundary is associated with the same reference frame as the fluid region, but Tangential Velocity Specification is set to a different velocity.

This setting is not compatible with the Circumferential Heat Flux Averaging model, Porous Media models, or Eulerian multiphase models except for the Volume of Fluid (VOF) model.

Segregated Energy Solver Properties

The Segregated Energy solver controls the solution update for the Segregated Fluid Energy model and for the Segregated Solid Energy model.

The following solver and solver options are available:

Segregated Energy
Fluid Under-Relaxation Factor, Solid Under-Relaxation Factor
In order to promote convergence, these properties are used to under-relax changes of the solution during the iterative process. If residuals show solution divergence and do not decrease, reduce the under-relaxation factors.
Solver Frozen
When On, the solver does not update any quantity during an iteration. It is Off by default. This is a debugging option that can result in non-recoverable errors and wrong solutions due to missing storage. See Finite Volume Solvers Reference for details.
Reconstruction Frozen
When On, Simcenter STAR-CCM+ does not update reconstruction gradients with each iteration, but rather uses gradients from the last iteration in which they were updated. Activate Temporary Storage Retained in conjunction with this property. This property is Off by default.
Reconstruction Zeroed
When On, the solver sets reconstruction gradients to zero at the next iteration. This action means that face values used for upwinding (Eqn. (905)) and for computing cell gradients (Eqn. (917) and Eqn. (918)) become first-order estimates. This property is Off by default. If you turn this property Off after having it On, the solver recomputes the gradients on the next iteration.
Temporary Storage Retained
When On, Simcenter STAR-CCM+ retains additional field data that the solver generates during an iteration. The particular data retained depends on the solver, and becomes available as field functions during subsequent iterations. Off by default.
Enable High-Accuracy Temporal Discretization
Provides the option of doing 2nd-order time discretization with four or five time levels. See Setting High-Accuracy Temporal Discretization.
