Modeling a laboratory channel used for training on controlling temperature and flow

Modeling is crucial in all design processes, since the construction of a model which simulates the process implemented on the ground allows for implementations and simulations of tests which may cut substantial costs in case of errors not observed by the designer during the design phase. This paper presents the detailed steps to build two mathematical models in Lab Volt 3522, the first for a duct shaped like Venturi tube used to train students on controlling airflow within it, and can be easily modified to be used with any required gas or liquid. The second is a model of a room of known size and dimensions, located within the designed duct, used to train students on controlling air temperature within it. This paper also shows the steps necessary to design the required PID controller to adjust the airflow value and temperature to match the required value.
