Abstract

Współczesne sale koncertowe z widowniami powyżej 1800 osób, prezentują szereg innowacyjnych rozwiązań przestrzennych. Mimo niewątpliwej różnorodności rzutów, większość z nich bazuje na planie Filharmonii w Berlinie, którą otwarto w 1963 r. W związku z zaobserwowanymi podobieństwami i różnicami w omawianych wnętrzach, powstających na przestrzeni lat 70. XX w., po początek lat 2000, w niniejszym opracowaniu zaprezentowano autorską typologię sal koncertowych o tzw. układzie centralnym z tarasami.

Abstract

We demonstrate in this study that a rotating magnetic field (RMF) and spinning magnetic particles using this kind of magnetic field give rise to a motion mechanism capable of triggering mixing effect in liquids. In this experimental work two mixing mechanisms were used, magnetohydrodynamics due to the Lorentz force and mixing due to magnetic particles under the action of RMF, acted upon by the Kelvin force. To evidence these mechanisms,we report mixing time measured during the neutralization process (weak acid-strong base) under the action of RMF with and without magnetic particles. The efficiency of the mixing process was enhanced by a maximum of 6.5% and 12.8% owing to the application of RMF and the synergistic effect of magnetic field and magnetic particles, respectively.
