This research aims to study the effect of the digester size on its thermal requirements in order to reach the optimal economic size to him. Where were studied a batch closed digester with solar collector, where he was measuring a thermal requirements at the same ambient conditions with the change of the size of this digester, in order to note the relative change of the heat requirements, and to get the optimal size that requires the least amount of energy in thermophilicanaerobic digestion.

Artificial intelligence review:
Research summary
يهدف هذا البحث إلى دراسة تأثير حجم المخمر على المتطلبات الحرارية اللازمة لإتمام عملية التخمير اللاهوائي باستخدام الطاقة الشمسية. تم استخدام مخمر دفعي مغلق مزود بلاقط شمسيّ، وتم قياس المتطلبات الحرارية له عند نفس الشروط المحيطة مع تغيير حجم المخمر. الهدف هو تحديد الحجم الاقتصادي الأمثل الذي يتطلب أقل كمية من الطاقة ضمن الشروط الحارة. تمت التجارب في المنطقة الساحلية باستخدام روث البقر المخلوط بالماء، وتم قياس درجات الحرارة المختلفة للمخمر والجو والخزان الحراري. أظهرت النتائج أن حجم المخمر المثالي يتراوح بين 10 و20 متر مكعب، حيث تكون الضياعات الحرارية عبر جدران المخمر أقل من 18% من الاحتياجات الحرارية الكلية. توصي الدراسة باستخدام لاقط شمسي واحد لعدة مخمرات لتقليل الفاقد الحراري وتحسين كفاءة التخمير.
Critical review
تعد هذه الدراسة خطوة مهمة نحو تحسين كفاءة إنتاج الغاز الحيوي باستخدام الطاقة الشمسية. ومع ذلك، يمكن توجيه بعض النقد البناء لتحسين البحث. أولاً، كان من الممكن توسيع نطاق التجارب لتشمل مناطق جغرافية مختلفة لتعميم النتائج. ثانياً، لم يتم التطرق بشكل كافٍ إلى التكاليف الاقتصادية المرتبطة بتصنيع وتركيب المخمرات واللاقطات الشمسية، وهو جانب مهم لتقييم الجدوى الاقتصادية. ثالثاً، كان من الممكن استخدام نماذج رياضية أكثر تعقيداً لتحليل البيانات بشكل أدق. وأخيراً، يفضل إجراء تجارب طويلة الأمد لتقييم استدامة النظام وكفاءته على مدار العام.

The research aims to take advantage of the solar energy, as a free energy, to run a water pump powered by solar energy, and to study the effect of the intensity of solar radiation on the performance of this pump in Syrian coast conditions. This resea rch has explained the necessary mechanism for determining the capacity of the pump and the electric PV panels required for the work of the pump and the area of these panels. Studying the effect of intensity of solar radiation on the performance of water pump through studying the impact of pump altitude and solar radiation intensity on water flow range at experiment location. It demonstrated that the flow of the pump is going through two phases with the increasing values of solar radiation during the day. It was found that the increasing value of the flow of the pump before the value of (520W/m2) of Solar radiation was greater than that after (520W/m2) and this led to the loss of a part of the solar energy falling during the day, especially on sunny days, and the value of the loss was about (27%) of the total amount of solar energy falling per day.
This research discusses the affecting factors of biogas production in the digester, to define the optimal temperature and suitable loading rate to achieve high digester biogas production. The research focuses on the water compressed continuous flo w digester (chines model), and the results is presented and illustrated in suitable tables and curves.
This research aims to study the effect of the tilt angle of PV panels on the daily discharge a water pump powered by solar energy, and to determine the optimal tilt of these panels during summer months in the Syrian coast. The results demonstrated t hat the change of the tilt angle of PV panels from (25˚) to (35.5˚), has no effect on the curve of the solar radiation intensity and flow rate. However the resulting impact was represented by low amount of solar energy falling onto PV panels, resulting in a reduction in hydraulic energy of the pump and consequently low flow rate per day. The study showed that the amount of water flow rate at the two angels (25˚ and 22˚) for the tilt of panels was close, with preference for the angle (22˚). Reduction of water amount from one month to another during the months (June, July, August) didn't exceed (2.5%), while it was (7.5%) in September. At angle (35.5˚), water amount was approximately constant during June, July and August, while it decreased by (6%) in September. Flowing water largely decreased at angle (35.5˚) in comparison with the two angles (25˚and 22˚), so the reduction was (13, 12, 9 and 7.5%), respectively in June, July, August and September.
This research includes analyzing and designing of high water tanks using elastic method. Also, analyzing the structural supporting system using the Second Equivalent Static Method, then analysis by using Linear Dynamic Method - Response Spectra M ethod utilizing Sap2000 program and performing necessary comparison.
The basic idea of the research is to deal with the problems facing floor solar heating systems (high Constituent cost, huge size of the storage tank, difficulty of implementation ...)in addition to fuel consumption. Despite the use of solar energy for the purpose of heating, that does not mean full dispensing for heaters assistance in order to increase the temperature of water in the days which the intensity of solar radiation is low.
