Heat Curves

About Heat Curves

Heat Curves are thermodynamic diagrams that display temperature vs. enthalpy and pressure vs. enthalpy data. They help you visualize the thermodynamic data for a fluid or across streams.

Concepts

• Unlike Trends and Profiles, Heat Curves appear only on the Canvas, not in the Simulation Manager

• The Heat Curve can reference a specified fluid, a specified stream, or conditions across two specified streams

• The Heat Curve displays data for only one fluid at a time

• The Heat Curve automatically updates when you switch between fluids or streams, change the fluid in the Fluid Editor, change the thermodynamic data for the fluid in AVEVA Thermodynamic Data Manager, or change the configuration of the Heat Curve

• The Heat Curve can display a single curve or multiple isobaric curves

• For single curves, the Heat Curve has two tabs, one for the temperature vs. enthalpy curve and one for the pressure vs. enthalpy curve

• For multiple isobaric curves, the Heat Curve has a specified number of tabs, one for each isobaric temperature vs. enthalpy curve across the specified pressure range

• Heat Curves display data in the units of measure (UOMs) that are specified in the UOM Slate for the Simulation

Actions

• Create a Heat Curve on the Canvas

• Select a Fluid Type or Stream basis for the Heat Curve

• Select a Fluid Type or Stream reference for the Heat Curve

• Switch between the tabs for the different curves

• Change the temperature range

• Change the pressure range

• Add a margin to the start and end values of the curve

• Select whether the Heat Curve displays a single curve or multiple isobaric curves

• Change the number of intervals on the curve

• Change the interval spacing for the curve

• Generate a Microsoft Excel report for the Heat Curve data

• Generate an HTRI data (.dat) file for the Heat Curve data
