NTNU Department of Chemical Engineering Objectives The main goals of the program are to develop new physical models for fluid flow computations, particularly focused on models applicable to design and optimization of chemical and metallurgical processes, and to strengthen the academic education and research in these fields at NTNU and SINTEF by: Graduating a minimum of 5 doctorates within these fields and strengthen the collaboration with international research groups through exchange on doctoral and post doc. level. Developing model programs and experimental validation tools for a selection of specific applications. Establish a graduate course in advanced reactor technology and multiphase flow. Strengthen the links between the fundamental and applied research, and the Norwegian industry.
