Research Outline

One project will focus on fundamental fluid mechanics and role of surface wetting properties in flow through small micro/nanoscale nozzles. The work will involve basic semi-analytical modelling as well as experimental validation. Low Reynolds number flows are dominated by viscous stresses. However for miniature nozzles wetting properties become important. This, for example, can lead to a droplet rising on a wettable needle rather than directly dropping down due to gravity. The project intends to understand these phenomena and use coatings on nozzle to overcome the challenges such as unwanted droplet rise on nozzles. A theoretical model of the droplet rise will be developed as an extension of the classical capillary rise problem, albeit happening on nozzle exterior and thus the fluid evaporation effect will have to be considered carefully. The model will be validated through droplet rise experiments on nozzles with different coatings. Another project looks at synthesising nano-composite based superhydrophobic surfaces to study the potential influences of superhydrophobicity on the reduction of bacterial colonization and subsequently the formation of biofilm

Biography

I was born and raised in Egypt where I did my undergraduate studies at the American University of Cairo, majoring in Mechanical Engineering. After that I did my MSc in Engineering with Finance at UCL in 2015 then I started my PhD in Mechanical Engineering in January 2017
