We are experimenting with delivering interactive simulations in a web browser. Source files and development tools are posted at our GitHub site. Our code structure is under development and the first two labs listed below have the most recent code.
Link – Dynamic diffusion and reaction in a porous solid catalyst. Project “reaction-diffusion” at GitHub.
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 such that the jacket dynamics affect the response somewhat. 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. Below is a static screenshot. Project “reactor-T-control” at GitHub.
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.
