Bendocapillary instability of liquid in a flexible-walled channel
نویسندگان
چکیده
We study the bendocapillary instability of a liquid droplet that part fills flexible walled channel. Inspired by experiments in which `weaving' pattern emerges as droplets are condensed slowly into deformable microchannels, we develop mathematical model this instability. describe equilibria system, and use combination numerical methods, asymptotic analysis limit small channel wall deflections, to elucidate key features find configurations always unstable perturbations sufficiently wavenumber, growth rate is highly sensitive volume channel, both wetting non-wetting susceptible same Insight novel interfacial instabilities opens possibility for their control thus exploitation processes such microfabrication.

با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولFaraday instability in a surface-frozen liquid.
Faraday surface instability measurements of the critical acceleration, a(c), and wave number, k(c), for standing surface waves on a tetracosanol (C24H50) melt exhibit abrupt changes at T(s)=54 degrees C, approximately 4 degrees C above the bulk freezing temperature. The measured variations of a(c) and k(c) vs temperature and driving frequency are accounted for quantitatively by a hydrodynamic m...
