Abstract AR
في هذا البحث، حسب الجريان فوق الصوتي الثلاثي البعد عبر مقذوفات بطريقة الفروقات المحددة لديناميك الموائع الحسابي.
لقد اعتبرت المسألة ذات جريان خارجي فوق صوتي لا أنضغاطي غير لزج عبر مقذوفات ثلاثية البعد مع كنرد تقليدي و بدون كنرد.
حلت معادلات أويلر باستخدام تكنيك مكورمك الظاهر مع الوقت.
ظروف الجريان أخذت عند مستوى سطح البحر مع عدد ماخ لغاية 2.5 للتعامل مع الشكل المعقد للمقذوفات، استخدمت نظام إحداثيات مطابقة الجسم بالطرق الجبرية و البيضوية لتوليد الشبكة عبر المقذوفات.
أظهرت النتائج تطابق جيد مع النتائج المنشورة.
Abstract EN
In this work, a three-dimensional primitive variable of supersonic flow over missiles was computed based on finite difference computational fluid dynamic methods.
The problem was considered is to deal with external, in viscid, compressible supersonic- flow over three-dimensional missiles with and without canard.
Euler equations were solved using time-marching McCormack's explicit technique.
The flow conditions are taken at sea level and Mach number was tested up to 4.0.
To deal with complex shape of missiles the so-called “body fitted coordinate system” was considered and the algebraic and elliptic methods were used to generate grids over missiles.
The number of iterations and the number of mesh points depending on Mach number.
The result indicate, that for the same Mach number, the increasing of mesh points, lead to increase of the number of iterations.
