DWSIM SIMULATION, KPR Institute Engineering and Technology, Autonomous Engineering Institution, Coimbatore, India

The event started at 11:45 AM due to overlap with paper presentation event. Dr. R. Bharathi Ganesan welcomed the students and inquired about the engineering stream of the students. All were 3rd and 4th year Chemical Engineering students of other Colleges. The resource person started by explaining what a chemical process simulator is and differentiated DWSIM from Aspen Plus viz. ease of availability to students. He explained how DWSIM was started by Daniel Wagner Madeiros in 2008 as a opensource software. He then listed what can be done in DWSIM to learn or do research and how dwsim is unique and relevant to chemical engineering students. Then he listed the basic steps involved in solving a problem using dwsim, showed the interface of dwsim and the basic classification of thermodynamic packages provided in dwsim. He also provided directions towards self learning of this software through spoken tutorial of IIT Bombay and Dr. P R Naren of Sastra University. By discussing the limitations of dwsim in handling polymers, solids, composite materials and biomass, the introduction session was over. Then a hands on solving of a chemical reaction problem was demonstrated by Student Coordinator Gowtheeswaran / CH III using Gibbs reactor. This part covered the entry of all compounds involved in the wizard, choosing an apt thermodynamic / property package, choice of system of units and defining the element matrix for the Gibbs reactor. He solved the problem and discussed about the results. Then Student Coordinator Vasanth P / CH III demonstrated the same problem using Conversion reactor by defining a new conversion reaction. Both the results were compared and the correct conversion was determined. It was ensured that all the Students solved both the problems. A brief result of dynamic simulation of water level in a tank was demonstrated by Dr. R. Bharathi Ganesan. With this the event concluded and many participants entered their anonymous feedback online in Google Forms itself. The participants collected their certificates and left to attend other Fiestaa events.
