Recommended Previous Knowledge:

Basic knowledge: Technical Thermodynamics

Educational Objectives:

Professional Competence

Theoretical Knowledge
  • The students are capable of explaining qualitative and determining quantitative heat transfer in procedural apparatus (e. g. heat exchanger, chemical reactors).
  • They are capable of distinguish and characterize different kinds of heat transfer mechanisms namely heat conduction, heat transfer and thermal radiation.
  • The students have the ability to explain the physical basis for mass transfer in detail and to describe mass transfer qualitative and quantitative by using suitable mass transfer theories.
  • They are able to depict the analogy between heat- and mass transfer and to describe complex linked processes in detail.
Capabilities
  • The students are able to set reasonable system boundaries for a given transport problem by using the gained knowledge and to balance the corresponding energy and mass flow, respectively.
  • They are capable to solve specific heat transfer problems (e.g. heated chemical reactors, temperature alteration in fluids) and to calculate the corresponding heat flows.
  • Using dimensionless quantities, the students can execute scaling up of technical processes or apparatus.
  • They are able to distinguish between diffusion, convective mass transition and mass transfer. They can use this knowledge for the description and design of apparatus (e.g. extraction column, rectification column).
  • In this context, the students are capable to choose and design fundamental types of heat and mass exchanger for a specific application considering their advantages and disadvantages, respectively.
  • In addition, they can calculate both, steady-state and non-steady-state processes in procedural apparatus.
  •  The students are capable to connect their knowledge obtained in this course  with knowlegde of other courses (In particular the courses thermodynamics, fluid mechanics and chemical process engineering) to solve concrete technical problems.

Personal Competence

Social Competence
  • The students are capable to work on subject-specific challenges in teams and to present the results orally in a reasonable manner to tutors and other students.
Autonomy
  • The students are able to find and evaluate necessary information from suitable sources
  • They are able to prove their level of knowledge during the course with accompanying procedure continuously (clicker-system, exam-like assignments) and on this basis they can control their learning processes.
