We are experimenting with delivering interactive simulations in web browsers. The top two labs have the most recent code structure, which is evolving. See our GitHub site for source code and development tools. Please email questions and comments to
Link – Dynamic simulation of an adiabatic packed-bed reactor with feed-product heat exchange. This combines the units in the two labs below. The system has feedback of energy and can exhibit multiple steady states and hysteresis. This system is related to an autothermal reactor.
Link – Dynamic simulation of a packed bed reactor with heat exchange.
Link – Dynamic simulation of a heat exchanger, both co- and counter-current. No reactions but you should find this interesting.
Link – Dynamic diffusion and reaction in a porous solid catalyst.
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.
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.
