The
Define/Periodic Conditions... menu item opens the
Periodicity Conditions panel.
Periodicity Conditions Panel
The
Periodicity Conditions panel allows you to set parameters that define fully-developed periodic flow and heat transfer. See Sections
9.4.3 and
13.4.3 for details.
(This panel is available only when the pressure-based solver is used; it is not available for the density-based coupled solvers.)
Controls
Specify Mass Flow
enables the specification of the mass flow rate.
Specify Pressure Gradient
enables the specification of the pressure gradient.
Mass Flow Rate
specifies the mass flow rate. This item will not be available if you selected the
Specify Pressure Gradient option.
For axisymmetric problems, the mass flow rate is per
radians.
Pressure Gradient
specifies the pressure gradient (
in Equation
9.4-3).
Upstream Bulk Temperature
sets the inlet bulk temperature for periodic heat transfer calculations.
Flow Direction
sets the direction of the periodic flow. The direction vector must be parallel to the periodic translation direction or its opposite.
Relaxation Factor
sets the under-relaxation factor that controls convergence of the iteration process described in Section
9.4.3 for specified mass flow.
Number of Iterations
sets the number of subiterations done on the correction of
in the pressure correction equation for specified mass flow. See Section
9.4.3 for details.
Update
updates the
Pressure Gradient field with the current value.
