Summary
Consideration is given to the stability of the flow of two power law liquids under the influence of normal electric field between two infinite parallel planes when one of the planes moves with constant velocity in its own plane. It is found that the electric fields have a dramatic effect and can be chosen to stabilize or destabilize the flow. The effects of the power law parameters on the problem are examined.
Riassunto
Si considera la stabilità del flusso di due liquidi secondo la legge di potenza sotto l’influenza di un campo elettrico normale tra due piani paralleli infiniti quando uno dei piani si muove con velocità costante nel proprio piano. Si trova che i campi elettrici hanno un effetto importante e possono essere scelti per stabilizzare o destabilizzare il flusso. Si esamina l’effetto dei parametri della legge di potenza sul problema.
Резюме
Рассматривается уст ойчивость потока дву х степенных жидкостей, находящихся под дейс твием нормального электрического пола между двумя плоскопа раллельными пластинами, когда одн а из пластин движется с постоянной скоростьюю относите льно другой. Обнаруже но, что электрическое поле и грает существенную роль и м ожет стабилизироват ь или дестабилизировать п оток. Исследуется влияние степенных параметро в на рассматриваемуюю пр облему.
