چکیده: (1059 مشاهده)
دیوارهای ساحلی یکی از روشهای حفاظت ساحل در مقابل فرسایش ساحلی و نیروهای مخرب امواج است. هدف این پژوهش شبیهسازی برخورد موج با دایک ساحلی و مقایسه نتایج با مدل آزمایشگاهی است. برای شبیه سازی میزان نیروی مستهلک شده ی موج توسط دایک ساحلی از نرم افزار متن باز Open FOAM و مدل آشفتگی K-ω SST استفاده شد. با در نظر گرفتن شرایط مختلف برای مدل سازی، مجموعاً تعداد 45 آزمایش جهت اجرای برنامه انتخاب شد. مدل سازی در دو شرایط کلی با سازه و بدون سازه و برای سه ارتفاع سازه، سه موقعیت متفاوت قرارگیری سازه و پنج ارتفاع موج انجام گردید. نتایج نشان داد که جذب نیروها نسبت به حالت بدون سازه افزایش پیدا کردهاند و میتوان گفت که وجود سازه توانسته تا 10 برابر نسبت به حالت بدون سازه در استهلاک نیروی موج نقش داشته باشد. شدت تغییرات نیروی وارد به سازه تابعی از ارتفاع موج است و با افزایش میزان ارتفاع موج این شدت تاثیر گذاری کاهش مییابد. تحت ارتفاعهای متفاوت موج هرچه سازه از مخزن ایجاد موج دورتر باشد میزان نیروی وارد به سازه کاهش مییابد.
