Welcome to Dr. Rao's Arena
Welcome to Process Modelling and Simulation module
The module presents a wide variety of concepts and techniques for developing process model and to simulate them at various operating conditions. Process simulation presents a model-based representation of chemical, physical, biological, and other technical processes and respective unit operations. Based on the prior knowledge of chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of a process in simulation software environment. This module also provides the knowledge of developing the process flow diagrams where unit operations are positioned and connected as per the feed and product streams. A thorough knowledge of development of models for a better representation of real processes is the core of this module.
