We are experimenting with delivering interactive simulations in a web browser. Please email questions and comments to    

Link – Dynamic simulation of a heat exchanger, both co- and counter-current. No reactions but you should find this interesting.

Link – Dynamic simulation of a packed bed reactor with heat exchange.

Link – Dynamic diffusion and reaction in a porous solid catalyst. Project “reaction-diffusion” at our GitHub site.

Link – Feedback control of temperature during reaction in a continuous stirred tank reactor (CSTR). The controller manipulates the temperature of the fluid entering the heat transfer jacket. At default conditions in manual control mode with constant inputs, the system oscillates. Do you know why the system oscillates? See the Resources tab, CRE Notes, 15 – CSTR thermal effects. Then put the system into Auto Control mode. Project “reactor-T-control” at our GitHub site.

Link – Reactor temperature control where the controller directly manipulates the heat transfer jacket temperature.

Link – Continuous, isothermal bioreactor (CSTR). Parameter values from Table 1 of Wu and Chang (2007) except gamma (p here) = 0.60. At default conditions in manual control mode with constant inputs, the system oscillates. Also see Alvarez-Ramirez, et al. (2009).

Link – Feedback control of water level in a tank.
