Time-Delay Identification and Validation of a Liquid Film Transport Model based on Pilot Plant Experiments

Hofmann, Julian; Ponomarev, Anton; Hagenmeyer, Veit; Gröll, Lutz

Abstract (englisch):

The paper presents an identification strategy to obtain relations between time
delays of a transport model for an evaporating liquid film and corresponding flow/liquid
properties. To this end, step-response based pilot plant experiments referring to the falling film
evaporator process are conducted. In this context, the time-delay relations are identified offline
by minimizing the output error between the model and experiment. In subsequent validation
experiments, we observe that modeled and measured outputs are in good accordance. Within
this framework, we conclude that the influence of evaporation on the liquid's time-delay behavior can be neglected.
