PhD Degree Awarded to Mr. Waleed Saleh Al-Jurbani – Department of Physics
Mr. Waleed Saleh Abdo Hasan Al-Jurbani was awarded a PhD degree in the major of Renewable Energy Physics for his dissertation titled “Performance Analysis and Optimization of Wind Turbines Suitable for Some Locations in Yemen,” which was submitted to the Department of Physics, Faculty of Science- Sana’a University. The PhD dissertation defense was held on Saturday, Dhu al-Hijjah 4, 1446 Hijri, corresponding to May 31, 2025.
The PhD Viva-Voce Committee, which was formed based on a resolution issued by the Post-Graduate Studies and Scientific Research Council, consisted of the following:
| # | Committee Members | Designation | Position |
| 1 | Prof. Mohammed Qasim Al-Mutawakel | Internal Examiner | Chair |
| 2 | Prof. Mohammed Ali Shukri | Main Supervisor | Member |
| 3 | Assoc. Prof. Riyad Mohammed Abdulbari | External Examiner | Member |
This dissertation aimed to evaluate the wind energy potential and economic feasibility for selected sites in Yemen, and identify suitable wind turbines for these locations.
The dissertation presented several key findings, including:
- Identifying the most appropriate and accurate numerical method for calculating Weibull parameters in some Yemeni sites.
- Assessing the wind energy potential and economic feasibility in various locations across Yemen.
- Selecting suitable turbines for 16 sites with high average annual wind speeds in the governorates of Saada, Al-Jawf, Amran, Sana’a, Hodeidah, and Taiz.
In his dissertation, Mr. Al-Jurbani concluded with several recommendations, such as:
- Continuing and expanding the study to cover all sites in Yemen.
- Emphasizing the government’s need to initiate the installation of some wind turbines, even small-capacity ones (ranging from 30-100 kW), in the locations identified by the study. This would serve as a practical trial for the study’s findings, along with installing monitoring devices to measure wind speed and other necessary data for future, more detailed studies on wind energy potential and economic feasibility.
- Recommending the diversification of electrical power sources, utilizing both wind energy and hybrid systems (wind + solar energy).
The PhD dissertation was examined and recommended by the Viva-Voce Committee for acceptance and approval. The PhD defense was attended by a number of academics, researchers, interested students, the candidate’s colleagues, and family members.
