Reactor temperature control - controller manipulates jacket inlet T

A 1st-order, essentially irreversible reaction in a continuous stirred tank reactor (CSTR). The controller varies the temperature of the heat transfer fluid entering the heat transfer jacket to control reactor temperature. Reactor volume = 0.1 m3, jacket volume = 0.02 m3, density = 1000 kg/m3, heat capacity = 2.0 kJ/kg/K.

Click the Run button to start. Hit the enter key or click out of field after changing inputs.

At default values in manual mode with constant inputs, the system oscillates. Then put into Auto Control.
