Abstract AR
يتناول هذا البحث دراسة الخصائص الهيدروليكي للجريان فوق الهدار المائل ذو القمة المركبة المتكونة من ربع دائرة و ذات حافة حادة تحت حالات الجريان الحر.
و لتحقيق الغرض أعلاه تم إنشاء نموذج لهدار ذو قيمة مركبة تم تثبيته عموديا و على زوايا انحراف (ͦ 35، ͦ45، ͦ60، ͦ90) مع محور القناة الطولي، و باستخدام عدة تصاريف لغرض إيجاد معامل التصريف لكل حالة.
لقد تبين من النتائج أن نموذج الهدار ذو زاوية انحراف ͦ35 يعطي أفضل أداء من الهدارات الأخرى ذات زوايا انحراف 45ͦ، ͦ60، ͦ90 و هذه النتيجة تتطابق مع الدراسات السابقة للهدارات نصف دائرية الحافة و الهدارات حادة الحافة.
Abstract EN
The hydraulic characteristics of a compound crested inclined weir which consists of both quarter round and sharp crest weir configuration under free conditions were studied experimentally in order to investigates the discharge coefficient Cd and the performance of weirs for discharge.
The experimental tests were carried out on a model of weir manufactured of compound crest shape fixed perpendicular and inclined with an angles 35°, 45° and 60° across the direction of flow in the experimental channel.
Number of flow discharge was dependent.
Results showed that the model with an angle of weir inclination of 35° with the center line of the channel had a better performance than the other models (i.e = 45°, 60° and 90°).
The conclusions concerning the flow characteristics over the compound crested weir agree with all the previous works on the semicircular and sharp crested weirs.
