Two identical systems were fabricated, each containing paraffin wax with different melting points, and experimentally tested under actual climatic conditions in Baghdad with varying water flow rates covering both laminar and turbulent flow regimes.<\/p>\n<p>The study also evaluated the charging, melting, and discharging characteristics of the paraffin wax during daytime and nighttime to provide new insights into the interaction between PCM behavior and flow conditions.<\/p>\n<p>The thesis concluded with several <strong>recommendations<\/strong>, including:<\/p>\n<ol>\n<li>Conducting <strong>annual tests under different climatic conditions<\/strong> to evaluate the long-term efficiency and reliability of the system.<\/li>\n<li>Integrating <strong>high thermal conductivity media or nanomaterials<\/strong> with paraffin wax to enhance heat transfer rates and storage efficiency.<\/li>\n<li>Using <strong>CFD numerical modeling<\/strong> to study heat transfer mechanisms and predict the optimal design of solar collectors integrated with PCM.<\/li>\n<\/ol>\n<p>This research activity supports one of the <strong>Sustainable Development Goals<\/strong>, specifically <strong>Goal 7: Affordable and Clean Energy<\/strong>, by developing practical solutions for a renewable and efficient thermal energy source.<\/p>\n<p>Following the scientific discussion by the committee members, reviewing the defense, and evaluating the thesis, the student was awarded a <strong>Master\u2019s degree in Energy Engineering with distinction (Excellent)<\/strong>.<\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_gallery interval=&#8221;3&#8243; images=&#8221;8736&#8243; img_size=&#8221;large&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] &nbsp; The College of Engineering at the University of Baghdad addressed the challenge of solar energy intermittency due &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.coeng.uobaghdad.edu.iq\/?p=8733\"><i class=\"fa fa-angle-left\" aria-hidden=\"true\"><\/i><span>\u0627\u0644\u0645\u0632\u064a\u062f<\/span><\/a><\/p>\n","protected":false},"author":165,"featured_media":8736,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"","_lmt_disable":"","footnotes":""},"categories":[37,31],"tags":[],"class_list":["post-8733","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-energy-engineering","category-thesis"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
