Industrial Physical Chemistry
Academic Year 2022/2023 - Teacher: LUISA D'URSOExpected Learning Outcomes
The course aims to deepen the basic chemical-physical knowledge for the understanding and investigation of chemical reactions and transport phenomena, a fundamental step for the design of chemical processes. Therefore, the applicative potentialities of the laws that regulate the transport of matter, energy and momentum will be presented. At the end of the course the student will be able to treat and solve through the direct numerical application of the studied relationships, problems concerning the motion of fluids, the transmission of heat and diffusion in the different chemical processes.
