Bashar Mahmoud


I started my Ph.D. in the School of Chemical and Process Engineering at the University of Leeds in 2015, after completing my M.Sc. and B.Eng. studies in the same school. Previous to my Ph.D. I worked as a Research Associate at the Kuwait Institute for Scientific Research (KISR), concentrating on Thermal Energy Storage (TES) for thermo-solar applications. Prior to that I worked as a Production Engineer at EQUATE (Joint Ventures - The DOW Chemical Company), and before that as a Gas Engineer at Kuwait Oil Company (KOC). My scientific motivations are based on my desire to become an independent researcher, who's willing to make a significant contribution to the global transition towards lower-carbon energy sources.

Research interests

My recent research focuses on developing novel types of molten salts with nanoparticles that can potentially be used as nano-heat-transfer and storage-fluid medium in solar thermal power plants. The intension is to improve the thermal property values of these salts, by doping them with minute concentration of metal-oxide nanoparticles. Special consideration will be given to assess the stability of embedded nanoparticles in the molten salt-base under agitation and repeated melting and solidification cycles, using appropriate diagnostic techniques developed at Leeds (Acoustic methods).

This innovative approach allows in-situ ultrasonic probes to be used to observe the dispersive properties of nanofluids, and to measure the changes of thermophysical properties of nanoparticle suspension via speed of sound variations. The study also aims to provide solutions to the challenges associated with the processing and transport of such nanofluid, whereby an advanced computational modelling and Direct Numerical Simulation (DNS) methods coupled to Lagrangian particle tracking is planned to be undertaken to study the hydro-transport phenomena of formulated nano-suspensions.

This would allow the prediction of nanoparticle aggregation, flow separation and profiles in different geometries of relevance, and hence their stability and flow properties. The overall aim of this research is to provide possible solutions to the challenges associated with the industrial use of nanofluids. Our approach of doing that is by combining the novel experimental development with the existing computational power. This in turn should lead to the provision of data and understanding that can be used for optimisation of the design, and operation of large-scale molten salt energy storage facilities, which are more Eco-friendly and cost-efficient.
