Temperature Series Dialog
Applicability: Cranium, Synapse (core versions 0315+)

The Temperature Series Dialog is used by the Composition-Temperature-Pressure Estimates Dialog to generate a series of state variables consisting of a fixed pressure, fixed compositions, and temperatures varying between specified limits.

Dialog Controls

The Temperature Series dialog provides controls for specifying fixed compositions, a fixed pressure, and a range of temperature values.

1
Property Control: displays the name of the physical property being estimated.
2
Number of Rows Control: displays the number of table rows into which the series values will be pasted. This number is initially equal to number of table rows selected in the estimates dialog.
3
Increment/Decrement Control: enables you to increment or decrement the number of rows into which the series values will be pasted.
4
Components Controls: displays the names of the components in the current mixture.
5
Composition Control: enables you to specify the fixed composition of each component.
6
Fixed Pressure Control: enables you to enter the fixed pressure that will assigned to each state variable set.
7
Starting Temperature Control: enables you to enter the lower limit of the generated temperatures.
8
Limit Type Control: enables you to select if temperature values will be generated between a starting and ending limit or will be incremented by a specified amount. See below for details.
9
Limit Amount Control: enables you to enter either the upper temperature limit or the increment used to generate temperature values. See below for details.
10
X Default Button: activates the Default Compositions Dialog which enables to select a default composition which will be entered into the composition controls. See below for documentation.
11
X Total Button: activates the Residual Composition Dialog which displays the current composition total and enables to assign the residual composition to an unassigned composition control. See below for documentation.
Ending Temperature or Temperature Increment

Temperature values can be generated between two limits, the starting temperature and the ending temperature, or by repeatedly incrementing the starting temperature by a specified amount. The dialog's Limit Type control specifies which type of series to generate.

Assuming the number of rows equals 6, the entries to the right would generate temperatures of: 0, 10, 20, 30, 40, and 50 C.

Assuming the number of rows equals 6, the entries to the right would generate temperatures of: 0, 5, 10, 15, 20, and 25 C.

Entering a Default Composition

A mixture's Default Composition Section may contain one or more compositions that can be accessed by various dialogs used by Cranium and Synapse. The Temperature Series Dialog is one such dialog.

Pressing the dialog's X Default button activates the default composition dialog.

Selecting a row in the Default Composition table control and pressing the OK button will insert the selected compositions into the Temperature Series dialog's composition controls.

Residual Composition Dialog

Pressing the dialog's X Total button activates the Residual Composition Dialog. This dialog can be used to view the current compsition total and insert a residual composition value into an unassigned composition control.

1
Composition Total Control: displays the total of all entered compositions.
2
Units Control: displays the Phase Equilibria Curve Point Dialog's currently selected composition units. Note that these units may be different from the current units being used in the application.
3
Residual Component Control: if there is only one component with an unassigned composition, this control displays that component's name.
4
Residual Concentration Control: if there is only one component with an unassigned composition, this control displays that component's composition that would bring the composition total to a value of 1 or 100, depending upon the current units.
5
Set Residue Button: if there is only one component with an unassigned composition and if there is a valid residual composition, pressing this button assigns the residual composition to the unassigned composition control.
