Conduits and conduit elements for transporting flowable media

摘要

The invention relates to conduits (1) which are used to transport flowable media. The inside of the conduit (2) which comes into contact with the flowable medium has a structured surface which enables a turbulent or quasi-turbulent boundary layer to be formed between the wall of the conduit and the main flow of said medium. The specially structured surface which is formed by high (4) and low (3) macroscopic and/or microscopic areas can increase the speed of the transported medium and the capacity to entrain particles which are contained in the transported medium or disposed on the wall of the conduit.
