Project goals
- Investigation, modelling and optimisation of various surface modifications with regard to their anti-adhesive and fouling-reducing effect
- Implementation of processes for coating and structuring the inside of heat exchanger tubes
- Experimental proof of the improved fouling behaviour on modified single pipes
Objectives of the sub-project of the Chair of Energy Process Engineering
- Detection of reduced fouling tendency of coated and structured surfaces
- Derivation of generally valid correlations between the energetic as well as topographic surface properties and the tendency to fouling
- Quantification of the increased fouling resistance on pipe inner surfaces
Expected advantages of the surface modifications to be developed compared to conventional heat exchanger surfaces
- Delay of mineral fouling processes during operation of heat exchangers
- As a result, the cleaning cycles can be increased and less oversizing of the heat exchangers is necessary
