An evaporation model for oscillating spheroidal drops

Enhanced evaporation from an oscillating liquid in a capillary tube

Oscillating and star-shaped drops levitated by an airflow.

We investigate the spontaneous oscillations of drops levitated above an air cushion, eventually inducing a breaking of axisymmetry and the appearance of "star drops". This is strongly reminiscent of the Leidenfrost stars that are observed for drops floating above a hot substrate. The key advantage of this work is that we inject the airflow at a constant rate below the drop, thus eliminating the...

On Modeling Evaporation of Sessile Drops

Evaporating drops and thin films have numerous applications, from nanometric photoresist films in semiconductor applications to small sessile drops used for analysis of DNA microarrays [1]. Evaporating sessile drops are particularly interesting due to nonuniform drop thickness and the presence of contact lines (separating liquid, gas and solid phase). These factors may lead to nonuniform evapor...

an application of equilibrium model for crude oil tanker ships insurance futures in iran

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
