Lecturer Hind Diya' Rida, a faculty member within the Department of Prosthetics and Orthotics Engineering at Al-Nahrain University, defended their doctoral dissertation at the University of Baghdad, College of Engineering on October 31, 2024. Mrs Rida awarded their doctoral degree with distinction.  The dissertation was titled: "Investigation of Prosthesis Constructal Cooling System Performance Using Hybrid PCM Heat Storage and Dissipation by Forced Cooling."

The defense was attended by Prof. Juma Salman Jiyad, Dean of the College of Engineering at Al-Nahrain University, as well as a large number of faculty members from both Al-Nahrain University and University of Baghdad.

The defense committee members were as follows:

·        Prof. Karima Ismail Amouri, University of Baghdad, College of Engineering (Chair and Supervisor)

·        Prof. Ahmed Waheed Mustafa, Al-Nahrain University, College of Engineering

·        Prof. Salah Sabeih Abdul-Kareem, University of Baghdad, College of Engineering, Al-Khwarizmi

·        Asst. Prof. Munther Abdullah Mousa, University of Baghdad, College of Engineering

·        Asst. Prof. Sajida Lutfah Ghashim, University of Baghdad, College of Engineering

The research focused on the design of a cooling system for a prosthetic limb using Constructal Theory for heat dispersion of phase changing materials. The design equations were derived with volume constraints and minimal pressure drop for the heat transfer fluid in a heat sink configuration, according to the theory. The theoretical, numerical, and experimental studies were conducted on a transfemoral amputation case. The results demonstrated that the optimal thermal performance occurred when the heat transfer fluid tube ends were positioned at the centers of tangential circles within the heat sink. Additionally, improved thermal performance was observed with increased branching complexity. The experimental results showed good agreement with the theoretical and numerical findings in literature.

The research led to the publication of four papers derived from the dissertation in journals indexed in Scopus (first and second quartiles).
