Algae raceway ponds are open-channel systems used to produce algae using sunlight and a source of nutrients. These systems are receiving increasing attention for their potential to be used as an affordable and sustainable source of high-nutrition food, by the cosmetics industry, or even as an alternative source of biofuel. However, in order to achieve economic feasibility and enable this transformation, the efficiency of these systems needs to be substantially improved. Mixing of gases and nutrients by turbulence within the raceway plays a central role in the efficiency of the system. Mixing prevents algae from settling onto the bottom of the raceway, ensures appropriate levels of exposure to sunlight and nutrients, and maximises gas diffusion and exchange between the raceway and the atmosphere. Currently, this is typically achieved by a simplistic approach, whereby paddle wheels enforce a minimum flow velocity within the raceway, which requires substantial energy input.
In this project you will first perform detailed analysis of mixing processes within existing raceway ponds. This analysis will then be used to create new, optimised designs of these algae production systems. We will be looking into innovative solutions for the design of both raceway ponds and corresponding propulsion systems. The work will be carried out through a combination of laboratory experimentation and numerical modelling.
The successful candidate will be based in the Department of Civil, Maritime and Environmental Engineering as part of the ‘Water and Environmental Engineering Group’ where you will join a vibrant team of students and researchers working in diverse areas of hydraulic and environmental engineering. The successful candidate will also work closely with our industrial partner, and may also conduct field surveys at a real-world, 400 m long raceway pond in South-West Morocco (although this will only be performed if deemed COVID-19 safe).
