✦ Synopsis


The present study introduces a new method in electronic descaling (ED) technology. In the proposed method, the ED apparatus consisted of a longitudinally positioned solenoid coil installed on an outer surface of a pipe. When electric current flows through the electric coils a magnetic field is generated whose direction is perpendicular to that of the flow direction. Experiments were performed at various Reynolds numbers. In order to monitor fouling at the heat transfer test section, the pressure drop across the test section and the overall heat transfer coefficient were measured as a function of time. The present study demonstrated an enhanced descaling effect of the longitudinally positioned solenoid coil while effectively inhibiting a formation of scales at slow flow conditions.

For the optimisation of a magnet design with cable-in-conduit conductor (CICC) technology it is essential to comprehend the scaling of the critical current from the separate strand characteristics to the finally assembled cable performance in a coil. Several model coils have been tested in the frame
