It was conducted on Wednesday, 3/9/2025, in the Dr. Ihsan Yahya Hall in the mechanical Engineering Department. the discussion of the master’s thesis of the student Narjes Ahmed Hussain, which is tagged:
” An Actual Transient Thermal Study for Integrated Collector-Storage Solar Hot Water Systems: Numerical Predictions, Experimental Testing, and Validation “.
The discussion committee consisted of names listed below:
1- Prof. Dr. Saba Yasoob Ahmed (Chairman)
2- Asst. Prof. Dr. Wisam Saadi Khudhair (Member)
3- Dr. Nawar Sabah Rasheed (Member)
4- Prof. Dr. Karima Esmail Amori (Supervisor)
this study concerned with preparing, instrumenting, and testing a new passive water storage tank integrated with a solar collector compatible to be used for residential, schools, hospitals, and other institutions.
The thermal performance of the storage solar collector water heating system is investigated experimentally and simulated using FLUENT ANSYS 2025 software. The continuity, momentum, energy equation and turbulence flow are covered in the simulation. The south oriented tank is made of two parts (inclined and horizontal) with combined volume 480 liters. All tank sides are thermally insulated except the inclined and upper horizontal surfaces, which are painted black and covered with glass panels. Field tests were conducted in Baghdad (33.3°E, 44.3°N) from May to November 2024, covering various load scenarios.
Here are the recommendations
- Promote system use in homes, schools, and hospitals to cut electricity demand.
- Improve insulation to reduce heat loss.
- Encourage local manufacturing to lower cost and ease maintenance.
- Apply in rural/off-grid areas as a low-cost solution.
- Extend research to winter operation, durability, and tank design optimization.
After the scientific discussion by the members of the discussion committee, the researcher received a rating of (excellent).
