Nonisothermal HI Reactor

In the case of a perfectly mixed nonisothermal system, you have to set up both the time-dependent material and energy balances. There are no spatial concentration gradients because the system is perfectly mixed, so the Reaction Engineering interface can create a model without evaluating the material-transport properties.

Danckwerts Benchmark - new

This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is fixed. The results with Danckwerts conditions and with fixed inlet concentrations are compared.
