حول قسم الهندسة الميكانيكية والصناعية

تأسس قسم الهندسة الميكانيكية والصناعية سنة 1961 ف وهو من أول الأقسام الهندسية في الجامعات الليبية وواكب القسم تطور الصناعة واحتياجات المجتمع من المهندسين في هذا المجال وعمل منذ إنشاءه على تخريج العديد من المهندسين الأكفاء الذين كانوا حجر الأساس لمسيرة التصنيع والإنتاج.

يضم القسم ثلاث شُعب هي شعبة القوى وشعبة الهندسة الصناعية والإنتاج وشعبة الميكانيكا التطبيقية؛ وتهتم شعبة القوى بكل ما يتعلق بالطاقة وتقنيات استخدامها ويندرج تحت ذلك نظريات وتقنيات انتقال الحرارة وميكانيكا الموائع والتبريد والتكييف ومحطات القوى وآلات الاحتراق الداخلي والطاقة الشمسية وطاقة الرياح وتحلية المياه وآلات الضخ وغير ذلك؛ بينما تختص شعبة الهندسة الصناعية والإنتاج بدارسة وتخطيط وتقييم طرق الإنتاج المختلفة وإيجاد الوسائل المثلى لإنتاج منتج ما مطابق للمواصفات من خلال مراقبة وضبط الجودة في مراحل الإنتاج المختلفة مع القيام بدراسات الجدوى الاقتصادية له؛ وتهتم شعبة الميكانيكا التطبيقية بالتصميم الميكانيكي (الإنشائي) للمنظومات والقطع الميكانيكية المختلفة بالسيارات والمصاعد ومحطات القوى ومصافي النفط وأنظمة المناولة وآلات الإنتاج والإنسان الآلي وغيرها.  كما تعنى هذه الشعبة أيضاُ بدراسة أساليب الحد من تأثير الإهتزازات والضوضاء و تهتم أيضا بوسائل وتقنيات التحكم الآلي والتصميم باستخدام الحاسوب.

Determination of Stress Intensity Factor for Different Crack Sizes using Finite Element Method

Abstract This Thesis overviews the methods for calculating the stress intensity factor and employs the stress and displacement methods in the current study. The model used simulates a cracked rectangular plate which is subjected to tensile stress. The Finite element method is used to calculate inplane displacement due to applied loads. As a post processing the stress and stress intensity factor over the plate was calculated. The results show that the singularity exists at the crack tip and the components of stress and approach infinity as the crack tip approach. The comparison of the current study to theoretical and other numerical results shows a good agreement and reliability of the program. The thesis consists of five chapters, the first chapter, presents general over view and historical al review. The second chapter demonstrates the theoretical basis in fracture mechanics. The third chapter involves the numerical solution using F.E.M. The fourth chapter demonstrates a case study and the results and discussion of the obtained results. The fifth chapter concludes the work and gives recommendations.

Analysis of Saharan Sand Abrasion of CSP Collector Surfaces

Abstract Many of the concentrating solar power (CSP) systems are expected be installed in desert locations where lack of water and sand storms might be an issue. The solar reflectors are considered to be among the main effective components. The negative effects of the harsh weather conditions, including sand storms of the desert might have strong influence on the reflector properties, leading to a decrease in the thermal performance of such solar system. This thesis studies the sand storm influence on solar reflector surfaces, where two different types of Libyan sands were considered and taken from sites suitable for the installation of CSP. These sands have different shapes, sizes and chemical compositions. Sand "A" has particle sizes that vary from 0.025 to 0.355mm, while Sand "B" has particle sizes in the range of 0.124-0.479 mm. An erosion rig was designed and built at Cranfield University, UK. the tests were conducted under different simulated sand storm conditions for both sand samples. The results have shown that Sand "A" has more severe influence than Sand "B" because the smaller particles of Sand "A" help the spread out over a larger surface area of the reflector. The higher sand storm speed has more strong impact influence, while increasing the mass quantity results in less consequences. The reflectivity of the un-cleaned surface drops by 5% in case of using Sand "A" and by 7% in case of Sand "B", both at storm speed of 21m/s with specific sand mass of 18g/m3.Sand storms with the speed exceeding 6 m/s, generate sand impact on the reflector surface causing degradation to the surface, while storms with speeds less than 6 m/s, result in wakes of suspended small particles as a consequence of the transport mechanism in the atmosphere. Sealing simulation and cleaning process, using Ultrasonic Cleaner Model, show that sand "B" makes a loss of about 3% of the surface reflectivity, due to the salt-chemical composition leading to create spots and marks on the reflector surface. However, Sand "A" has recorded no chemical reaction. Sand storm history should be taken seriously, reflector surface materials should be suitable for the sites, and cleaning operations should be considered.

Investigation into the Decision Making Processes within Some Operating Oil & Gas Companies

Making decisions is considered as the key role in achieving the desired goals within any organization. Moreover, making decisions in oil & gas industry is becoming a key factor for improving the work performance throughout practicing the most effective tools and techniques. The main purpose of this paper is to identify how individuals making their decisions within operating oil and gas companies. The required data for this paper were acquired by conducting several interviews with decision makers, and a questionnaire survey was also developed, besides reviewing the related literatures. Decision making processes in Libyan oil & gas operating companies were being investigated. The main findings show that over half of participants always consider safety, security and uncertainty issues when making their decisions, meaning that, it is a good indication of taking precautions when making decisions. Additionally, the majority of participants always double check their information resources, which is also a good indication of increasing the quality decisions and enhancing the work performance. Based on the findings, a number of recommendations were proposed for improving the processes of making proper and effective decisions within this business area arabic 13 English 77
