Doctoral Dissertation in College of Mechanical Engineering Discusses an Experimental Study of Heat Transfer Using Nanofluids

The College of Mechanical Engineering at the University of Technology examined an PhD dissertation, entitled: “Experimental study of flow boiling heat transfer in a microchannel using Nanofluids.”

The dissertation, presented by the student Shahid Mahdi Talib, investigated methods of improving thermal performance in single-phase flow by analysing the heat transfer coefficient, and in two-phase flow by studying flow boiling characteristics, including the heat transfer coefficient, critical heat flux, and instability. This was achieved using single and hybrid nanofluids, under a range of heat fluxes and mass fluxes, and under operating conditions below the saturation temperature. Furthermore, the study examined the effect of the type of single nanofluid, as well as the effect of hybrid mixtures composed of a dual blend of: silver with carbon nanotubes, silver with graphene platelets, and carbon nanotubes with graphene platelets.

The examining committee consisted of: Professor Dr. Abdul Hassan Abdul Karam Allah (Chairman), Professor Dr. Sattar Jaber Habib, Professor Dr. Abdul Sattar Jawad Mohammed, Professor Dr. Raheeq Ismail Ibrahim, Assistant Professor Dr. Ali Lafteh Kaeed (Members), and Professor Dr. Ikhlas Mohammed Fayyad and Assistant Professor Dr. Muayyed Razouqi Hassan (Supervisors).
