Processes in energy, environmental and process engineering can be visualised as balance flows of the physical conservation variables mass, energy and momentum. To carry out these processes, systems for conveying, mixing, separating, material conversion and heat transfer must be designed. This course teaches the fundamentals of balancing and heat and mass transfer.

• Fundamentals of balancing
• Integral and differential balancing of the total mass and the mass of a substance type
• Mass transport by diffusion
• Integral and differential energy balancing
• Heat transfer by conduction and radiation
• Applications to practical examples of apparatus dimensioning (e.g. heat exchangers)
• Similarity theory - dimensional analysis and model tests

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination or
• oral exam

Written examination with calculation tasks and question section, alternatively an oral examination or a term paper can be offered.

The examiners choose the type of examination from the options provided and inform the students at the beginning of the semester.

Written eximation: 2 Hours

Knowledge of differential and integral calculus, basic knowledge of thermodynamics and chemistry.

Students at Osnabrück University of Applied Sciences who have successfully completed this module have basic knowledge of mass and heat transport, balancing and similarity theory. They are able to balance simple
processes and apply the elements of similarity theory to simple examples for the design and scale-up of process engineering plants.

Students have an understanding of process engineering processes. They are able to carry out and explain balancing of process engineering processes, taking into account material and heat transport.

Students are able to scrutinise and evaluate the balancing methods given in the literature for selected processes.

Students will be able to derive simple tasks for dimensioning process engineering systems on the basis of idealised assumptions on material and heat transport and taking into account the elements of similarity theory.

Students can competently discuss with representatives of other disciplines both the material and energy balancing of process engineering processes and the design of process engineering equipment on the basis of criteria equations.
