Class ReactorAxialProfile

java.lang.Object
neqsim.process.equipment.reactor.ReactorAxialProfile
All Implemented Interfaces:
Serializable
public class ReactorAxialProfile extends Object implements Serializable
Container for axial profiles from plug flow reactor simulation.

Stores temperature, pressure, conversion, molar flow, and reaction rate profiles along the reactor length. Provides interpolation and export methods for post-processing and visualization.

Usage example: 

PlugFlowReactor pfr = new PlugFlowReactor("PFR", feed);
pfr.run();
ReactorAxialProfile profile = pfr.getAxialProfile();
double[] temps = profile.getTemperatureProfile();
String json = profile.toJson();
