SetName ยป |
|||
---|---|---|---|
The SetName Node is used to enter the data for each experimental set. Here you may add, delete, and include Data Points. When there are many data points, it may be easier to add multiple data points through the Add Data Point action, and then copy the values from a spreadsheet into the cells in the grid.
Tabbed ViewsThis node has one Total Moles (or Total Mass) tab, plus a tab for each Phase defined in the project. For CSTR reactors, additional tabs related to intermediate feed or separation may also be enabled. By default, this node shows the experimental data for one set. If the sets are merged, then this node shows the experimental data for all sets in a single node.

Total Moles
Top of Topic The Experimental Data grid is used to add the experimental data for the set, and is organized as follows:
When you open the Description pane, a picture is shown to facilitate the loading of experimental data for a given CSTR configuration. For example, the following schematic corresponds to a CSTR series with Intermediate Feed and Separation enabled: Data Organization for PFR reactors: If you select PFR reactor, at least two data points (inflow and outflow) must be entered in each experimental data set. The first data point contains the information of the PFR's inflow, and the following data points correspond to the points along the length of the PFR. The experimental data should follow the rules below:
Adding a Data Point When a new set is added in the Experiments node, it automatically contains two Data Points. You may add Data Points directly or through the Add Data Point action.
Deleting a Data Point You may delete a Data Point by selecting the Data Point row and using the <DELETE> key. A message box will appear asking if you are sure to delete the Data Point. Click OK. Note: You may run Checkmodel to verify that the experimental data have been entered correctly.
Total Mass
Top of Topic The tab is shown when Mass Density is selected as units of concentrations in Units Configuration node, and behaves exactly same to the Total Moles tab.
Phase
Top of Topic The Phase tab is used to enter all the variables that have been selected as measured in each phase in the Measurements node. These tabs are organized almost identically to the Total Moles tab.
Description
This pane is available only for CSTR reactors, and is just a pictorial aid. The main purpose here is to graphically relate streams in the CSTR series with the CSTR Points in the grids, where the information is to be provided. The appropriate streams are dynamically highlighted as you activate the different tabs in this node. Top of Topic
Intermediate Feed
This tab only appears for CSTR reactors with Intermediate Feed enabled in the Reactor node. All compounds are listed in columns, and you may specify the amount of intermediate feed added at each CSTR point. When Use Energy Balance is enabled in the Reactor node, the Temperature column appears for each intermediate feed stream. You may activate the Description pane to ensure that the data is specified for the correct streams. Top of Topic
Intermediate Separation
This tab only appears for CSTR reactors with Intermediate Separation enabled in the Reactor node. The layout here depends on the selected separation option. For Overall Based separation, all compounds are listed in columns so you can enter the percentage removal for each compound at the CSTR point. For Phase Based separation, all phases are displayed, so you may specify the percentage removal of each phase. Top of Topic Actions Add DataPoint Sort Data Remove Gaps Quick Run Open Solver
Add DataPoint
This action is used to add data points. By executing the Add Data Point action, a parameters dialog appears asking you for the number of Data Points to be added. Enter this information and click Ok to generate the datapoints for this set. This action is also available on the Node Menu, as shown in the green highlighted area in the figure below. Sort Data When Sort Data is executed, the data points are reorganized in ascending order of the discretized variable. This sort also ensures that datapoint consistency is maintained throughout the project. After Sort Data is executed, all the data from the Results tree is deleted and you need to run the project again. Remove Gaps When Remove Gaps is executed, gaps in the datapoint sequence are eliminated. For example, if you have consecutive datapoints 8,10,11 and 12, the points 10, 11 and 12 are renumbered as 9, 10, and 11 respectively. Again, the gap removal is done systematically throughout the project, thus ensuring that datapoint consistency is maintained. After Remove Gaps is executed, all the data from the Results tree is deleted and you need to run the project again. Top of Topic See Also: |
