Abstract
Fluidic devices built from suitable refractory materials can withstand the extreme conditions encountered in flows of molten metals - even those with a high melting point. This paper informs about the hydrodynamic aspects of a recent development of a fluidic controller keeping the metal gravity flow constant. The controller uses a narrow notch weir for generating the control signal and a fluidic vortex valve as the actuator. An unusual feature is the signal transfer between the two components performed also by a molten metal flow. It is even possible to amplify the signal using the liquid metal as the working medium in the amplifier.
يمكن للأجهزة المائعية المصنوعة من مواد حرارية مناسبة أن تتحمل الظروف القاسية التي تواجهها تدفقات المعادن المنصهرة - حتى تلك ذات درجات الانصهار العالية. وتستعرض هذه الورقة البحثية الجوانب الهيدروديناميكية لتطوير حديث لمتحكم مائعي يحافظ على ثبات تدفق المعدن بفعل الجاذبية. يستخدم المتحكم هداراً ذا ثلمة ضيقة لتوليد إشارة التحكم، وصماماً دوامياً مائعياً بصفته عنصراً مشغلاً. وتتمثل إحدى السمات غير المألوفة في أن نقل الإشارة بين هذين المكونين يجري أيضاً عبر تدفق المعدن المنصهر، بل إنه من الممكن تضخيم الإشارة باستخدام المعدن السائل بوصفه وسط التشغيل في المضخم.
