a.plica.ion of ma.netic flux controllers/concentra.ors to induction hea.ing coils ca. dra.tica.ly improve the process efficiency a.d hea. pa.tern control. Presenta.ion includes: benefits provided by flux controllers, ma.eria.s a.a.la.le for controllers, a.plica.ion techniques, computer a.sisted design of induction coils with concentra.ors, exa.ples of a.plica.ions. Depending on induction system design, ma.netic flux controllers ca. concentra.e hea.ing in a.specified a.ea. cha.ge hea. source distribution a.d shield a.pa.ticula. pa.t zone or externa. a.ea.preventing unintended eddy current hea.ing. Besides of the coil efficiency improvement a.d optima. power distribution, ma.netic flux controllers reduce the coil current dema.d from a.supplying circuitry thus strongly reducing losses in busswork, ca.les, tra.sformers a.d inverter components. Improvement tha. ca. be a.hieved due to ma.netic flux controllers is ca.e dependa.le. 2D a.d 3D computer simula.ion a.lows the designer to predict a.cura.ely effect of controllers on the coil pa.a.eters a.d tempera.ure distribution a.d optimize the whole electroma.netic system. Specia. a.tention in presenta.ion is pa.d to new ma.netodielectric ma.eria.s optimized for induction hea.ing conditions. These ma.eria.s ha.e high ma.netic permea.ility a.d sa.ura.ion flux density, excellent ma.hina.ility, good chemica. a.d tempera.ure resista.ce. Concentra.ors from these ma.eria.s ca. work in a.wide ra.ge of frequencies a.d specific powers. Exa.ples of ma.netic flux controller a.plica.ion include surfa.e ha.dening of sha.ts a.d gea.s, induction surfa.e ha.dfa.ing a.d bra.ing.

In this pa.er, the flow pa.terns observed in horizonta. Couette-Ta.lor flow（CTF） were correla.ed using dimensionless numbers. The a.a.ysis of the results showed tha. the structure of the flow wa. a. outcome of intera.tion between fluid inertia.rela.ed to a.ia. a.d rota.iona. flows a.d gra.ita.ion. Therefore, the flow structures were correla.ed using a.ia. a.d a.gula. Reynolds numbers, a.d a.chimedes number for the given va.ue of ga.-to-liquid flow ra.io. Fina.ly, the correla.ion for the prediction of the tra.sition to the flow regime observed a. high rota.iona. speeds wa. proposed. The compa.ison with experiments ca.ried out in the vertica. CTF from the litera.ure showed tha. this correla.ion ca. a.so be useful in the ca.e of vertica. flow.
