GOMEZ, CÉSAR AUGUSTO; CALDERON, YUDY ALEXANDRA  e  ALVAREZ, HERNÁN. BUILDING PHENOMENOLOGICAL BASED SEMI-PHYSICAL MODELS: FERMENTATION PROCESS CASE. Rev.Bio.Agro [online]. 2008, vol.6, n.2, pp.28-39. ISSN 1692-3561.

This work presents a method for building Phenomenological Based Semiphysical Models (PBSM). The method is based on transport, transfer, transmission or transit phenomena and conservation principle. A detailed description of proposed method steps is given. Next, the method is applied to attaining a model for describing the behavior of five dynamics (volume, biomass, substrate, product and temperature) of a continuous fermentation process. Model simulation shows that obtained model can predict dynamic performance of real process adequately.

Palavras-chave : Modeling; fermentation process; semiphysical models; process dynamics.
