إنَّ ازدياد الطلب على الطاقة و المشاكل الناجمة عن تلوث البيئة أدى إلى التوجه لرفع كفاءة استخدام الطاقة من خلال الأبحاث العلمية المرتبطة بالطاقات المتجددة. خاصة أنَّ سورية تتمتع بإشعاع شمسي عالي و زمن سطوع شمسي طويل. يتركز البحث حول تحديد الكفاءة الحرارية لنموذج مركز شمسي خطي قطعي (PTC) بهدف الحصول على النموذج الأمثل حرارياً و اقتصادياً وفق الشروط المناخية لمدينة دمشق. تم وضع نموذج رياضي للمركز المدروس وفق الأبعاد التصميمية المحسوبة من خلال حل معادلات الزوايا الشمسية و الإشعاع الشمسي المباشر على مدار السنة. و قد تم حل هذا النموذج باستخدام عدة برامج حاسوبية (Excel, EES).
The drastically increase in energy demand and the problems resulted from environmental pollution have led to a serious trend towards energy utilization efficiency improvement through scientific researches related to renewable energies, particularity that Syria has a high solar irradiance and prolonged sunshine hours. This research focuses on determining the thermal efficiency for a prototype of a parabolic trough solar concentrator (PTC) to obtain the optimal prototype thermally and economically according to climatic conditions in Damascus. It has been deposited the mathematical model of the studied concentrator depending on the calculated design parameters through calculating the solar angles equations and direct solar irradiance throughout the year. And it has been solved this model by using numerous computer programs (Excel, EES).

Direct steam generation in parabolic trough collector (DSGPTC)
has had a great importance because of its thermoeconomic
advantages and many researches have be done in
this field. Due to that reason this paper studies the convection
heat transfer
from absorber tube of a PTC to all phases of
water (liquid water, wet steam and dry steam) along the
whole distance of fixed length of a DSG-PTC generates a high
temperature superheated steam (561 °C). All heat transfer
operations in PTC has been modelled and then the
convection' components which are; fluid temperature, tube
wall-fluid temperatures difference and heat transfer
coefficient have been analyzed in details at different
operation conditions such as inlet fluid pressure, direct solar
beam and mass flow.
This research shows the necessity of building the solar electric generating system to provide a clean renewable energy and to meet people's needs of electrical energy at Peak-Load to keep a clean environment in Palmyra region. This paper concluded a
study of electric generating power plant with 30 MW capacity during day. A part of heat power collected in a solar field is stored in sensible thermal energy storage for covering Electrical Peak Load when the plant operates at night. This research showed the advantage of constructing the solar system with a Parabolic Trough in the solar
field. The amount of heat collected during months of the year is high and the hours operating at daytime were great. The building of solar-electric plant is valid technically and economically. This research performed a design of solar field and its Parameters using Computer Program (Language C++) and calculated the most important plant
performance during months of the year.
The research includes the main ideas, outline and
preliminary structure for designing the proposed thermal
hydraulic autonomic solar tracker.
Who enjoys the benefits outweigh known trackers, raising
yields and minimize energy expended, reduced vi
bration
through hydraulic movement. This makes the suggested
tracker outweigh the Clifford-Eastwood-Tracker.
Disadvantages of the proposed Tracker also much lower than
the disadvantages of known passive trackers for variable
intensity of solar radiation including the effect of clouds.
The thermal exchangers are widely used in the power generating stations and many
refrigeration systems. Activity in the thermal cycle depends on its design and real
calculations.
The aim of our present work, is to find an ideal calculation method
of the working
exchangers parameters and evaluating the used technical engineering soluting.
We discussed the ideal chosen problems and the affecting parameters, and used a
calculating design for a thermal exchanger in the heating and feeding with hot water,
considering these parameters. The proposed designing benefit, could be evaluated from the
final indication that could be expressed by real palpable material.
We found that the ideal parameters choosing could clearly descrese the preparation
costs the heat exchanger blank – form by three times and give full clear proposed
calculation method of all the parameters and its exchanging. This could save of the best
exchanging possibility chosen from the different exchanger.
The process of direct steam generation was studied in this work
within a parabolic trough solar collector in order to generate
electricity. The study was based on the equations of a two phase
flow to study heat transfer in the collector's tube. Th
e study showed
a possibility to reach an effective model to study the performance of
this type of solar collectors which will aid in the understanding of
the working principle of power plants and to research further
towards new control strategies of solar power plants or towards the
hybridization with other types of power plants.
