wT  (Polymer mass fraction, Temperature curve)

Top  Previous  Next

Experimental data for solvent/polymer systems are often given as either (Polymer mass fraction, Pressure) or (polymer mass fraction, Temperature) curves.

This function lets the user trace the cloud point curve at fixed pressure as a function of polymer mass fraction while the solvent ration is constant.

 

Input

Argument

Type

Optional

Description

Feed

Range of double

No

A range of cells with the feed

 

Direction

 

C# : string

 

No

Direction in polymer mass fraction. Valid input are:

Up

Down

InitialMassfraction

C# : double

No

Polymer mass fraction where the curve starts.

Pressure

C# : double

No

Fixed pressure.

MinimumTemperature

C# : double

No

Is used when calculating the first point on the curve. Lowest possible temperature.

MaximumTemperature

C# : double

No

Is used when calculating the first point on the curve. Highest possible temperature.

Output

C# : string

No

Defines the output for each point on the curve. See here for more information.

 

Components

 

C# : string

 

No

Give a list of component names.

Only those components are used in the calculations.

Units

 

C# : string

 

No

 

Set the units used in this calculation.

Distribution

C# : object

(Expect a range of double)

Yes

Gives a range with the distribution of the polymer. Can for example be used if 2 flash calculations are liked as 2 separation tanks.

BlockMassfraction

C# : object

(Expect a range of double)

Yes

Sets the block mass fractions in a co-polymer.

ProjectSheet

C#: object

Yes

Lets the user set the project sheet to use.
