Course Content (Syllabus)
The course will present the theoretical and applied background for the understanding of mass, energy and momentum transport phenomena but will focus on mass transport for energy applications. Both microscopic as well as macroscopic structures will be presented so that the students can understand the common principles underlying all transport phenomena and their properties, with emphasis on diffusion processes. Introduction: Basic principles and definitions. Differential forms of the equations of mass and energy transport. Commonly used boundary conditions. Phenomenological theory of molecular diffusion and Fick's first law. Concentration distributions for fluids at rest. Diffusion with homogeneous and heterogeneous reactions. Relative influence of rates of mass transport and reaction. Gas diffusion in porous media: molecular diffusion, Knudsen diffusion and viscous flow. Convective mass transport: Non-dimensionalization and non-dimensional numbers in mass and energy transport. Various examples and simplifying assumptions. Reynolds and Peclet numbers, turbulent diffusion. Analysis of the differential and integral forms of the conservation equations in closed and open systems. Use of numerical techniques for the computational solution of mass transport phenomena. Numerical techniques for the solution of unsteady, combined mass and energy transport phenomena using finite differences in the possible presence of chemical reactions.

Student Assessment
Description
The final grade is obtained from the composition of the grades in one project which is completed during the semester and is examined orally, one written midterm exam and one written final exam. The algorithm used for the calculation of the final grade is 0,2* project grade + 0,3* midterm grade + 0,6* final exam grade
Student Assessment methods
• Written Exam with Short Answer Questions (Formative, Summative)
• Written Exam with Extended Answer Questions (Formative, Summative)
• Written Assignment (Formative, Summative)
• Oral Exams (Formative, Summative)
