Background: It is proposed to set a traveling magnetic field in a special control channel (beam, pipe), coupled with several controlled channels - small-sized maglev systems in which levitation of transport modules is carried out. Aim: to interface the control channel with several controlled channels (up to four) small-sized maglev systems. In this case, the control channel will be located in the center, and the controlled channels at the top, right, bottom, left. Methods: 3D-modeling, layout, spatial composition, patent search. Results: The traveling magnetic field in the control channel is created by a moving sequence of interacting magnetic field sources the movers, which interact too with magnetic field sources of transport modules the fellow travelers, levitating in the controlled channels through sources of a constant magnetic field. The structure is installed on arched supports that uniformly distribute the load over the support surface. A model of a two-channel system with a lower location of a controlled channel has been developed. Conclusion: The small-sized maglev systems can form a multi-channel transport system.

Traveling Magnetic Field

Non steady applied magnetic field impact on a liquid metal has good prospects for industry. For a better understanding of heat and mass transfer processes under these circumstances, numerical simulations are needed. A combination of finite elements and volumes methods was used to calculate the flow and solidification of liquid metal under electromagnetic influence. Validation of numerical results was carried out by means of measuring with ultrasound Doppler velocimetry technique, as well as with neutron radiography snapshots of the position and shape of the solid/liquid interface. As a result of the first part of the work, a numerical model of electromagnetic stirring and solidification was developed and validated. This model could be an effective tool for analyzing the electromagnetic stirring during the solidification process. In the second part, the dependences of the velocity pulsation amplitude and the melt velocity maximum value on the magnetic field pulsation frequency are obtained. The ability of the pulsating force to develop higher values of the liquid metal velocity at a frequency close to the MHD resonance was found numerically. The obtained characteristics give a more detailed description of the electrically conductive liquid behaviour under action of pulsating traveling magnetic field.
