چکیده

شناخت دینامیک شناورهای تندرو در آب آرام و امواج، حائز اهمیت فراوان است. با تعیین ضرایب معادلات حرکت، می‌توان دینامیک شناور و عوامل مؤثر بر ناپایداری آن را شناخت و در جهت کنترل این ناپایداری‌ها اقدام کرد. هدف اصلی در این پژوهش تعیین ضرایب هیدرودینامیکی حرکت طولی شناورهای تندرو کاتاماران با استفاده از CFD و همچنین پاسخ به این سؤال که المان کنترلی اینترسپتور چه تأثیری بر ضرایب هیدرودینامیکی شناور کاتاماران تندرو دارد؛ است. تعیین ضرایب هیدرودینامیکی به‌روش تجربی هزینه‌بر بوده و نیاز به تجهیزات آزمایشگاهی دقیق دارد، بنابراین استخراج این ضرایب به‌روش عددی و ایجاد آزمایشگاه مجازی می‌تواند مفید باشد. در این تحقیق به استخراج ضرایب هیدرودینامیکی یک کاتاماران بدون و با اینترسپتور پرداخته شده‌است. نتایج، نشان‌دهنده مستقل بودن اکثریت ضرایب از فرکانس، به‌خصوص در فرکانس‌های بالا است. همچنین تأثیر اینترسپتور بر ضرایب نیز در فرکانس‌های مختلف به‌جز موارد اندکی قابل چشم‌پوشی می‌باشد.
