Modeling and dynamics analyses of immobilized CSTR bioreactor using transfer function model

CSTR (Continuous Stirred Tank Reactor) is commonly used in case of immobilized enzyme or immobilized cells. Mathematical model is a useful tool in reactor design, operation condition optimization, and production process automation. Transfer function relates the output and the input and reflects the dynamics of the system. Laplace transforming can make the differential equations into algebra equations, simplifies the solution of the model. In addition, transfer function is simple, easy to use, and able to predict the outputs of various inputs without modification of the transfer function. In this paper, the transfer function for CSTR with immobilized biocatalysts is built as an example for transfer function building and system dynamics analysis.
