Streams flows interaction in a complex CSHT system

Review on control process studies and teaching methods shows that majority of the scenarios presented and discussed correspond to restricted operation conditions. So, wider and deeper understanding of the interaction between different variables of the actual system is required in order to enhanced the knowledge of new professionals. This work presents the fluid interaction of three flow streams and their characteristics inside a continuous stirred heated tank (CSHT) when it is assumed that characteristics at the exit stream are the same as the characteristics inside the CSHT. Novelty of this work is fact that all four variables: temperature, composition, liquid level inside the tank and mass flow are considered simultaneously for the three streams. Model combines all three governing equations; mass, species and energy conservation laws, for a constant section area tank using MatLab Simulink ®. Discharge velocity follows Torricelli's law. Model main constrains is defined by the assumption of having density and specific heat capacity as constants. The behaviour of the system can be determined successfully by the developed model. Interconnected temperature, exit mass flow, volume and concentration are determined.
