چکیده

پس از تعریف حالت تعادل براساس تابع انرژی آزاد مناسب و تلفیق آن با الگوریتم شبکۀ بولتزمان، سیستم دوفازی بخار – مایع مدل سازی شده است که رفتار آن از معادلات پیوستگی و ناویر – استوکس پیروی می کند. به کمک مدل توسعه یافته ابتدا سطح تماس مسطح (Planar Interface) حل شده و نتایج با نتایج تئوری مقایسه گردیده است. سپس قطرۀ معلق در فضای بخار تحت بررسی قرار گرفته و نتایج به دست آمده برای قطرۀ پایدار با نتایج تئوری مقایسه شده است.
