Particle-droplet collisions – fundamentals to application

The EPSRC Centre for Doctoral Training in Future Fluid Dynamics is now recruiting to this fantastic PhD opportunity in partnership with Danone, Proctor & Gamble and Nestle.<br /> <br /> As a student on the CDT you will participate in a four-year programme that combines an integrated MSc (completed over the first two years) paired with a three-year PhD-level research programme. This gives you a combination of bespoke taught modules and inter-disciplinary research training.<br /> <br /> You will be part of a supportive cohort of research students with different academic backgrounds, all focusing on different aspects of Fluid Dynamics. During the taught aspects of your course you will receive a range of tailored seminars, lectures and practical laboratories to cover the computational, experimental and analytical aspects of Fluid Dynamics. This provides you with a strong background to the fundamentals of Fluid Dynamics. In addition you will have access to a wide range of personal development activities.

<p>Please visit the <strong><a href="https://fluid-dynamics.leeds.ac.uk/">EPSRC Centre for Doctoral Training in Future Fluid Dynamics</a></strong> website to find out more about the programme.</p> <p><strong>The PhD Project: Particle-droplet collisions – fundamentals to application </strong></p> <p>Collisions between particles and droplets are important in numerous natural and industrial systems.  To predict the behaviour of these systems a better understanding of binary droplet-particle collisions is required. This project builds on our previous work at UoL which developed novel experimental techniques and used energy-based scaling analysis to understand and predict collision outcomes. This project will extend this fundamental understanding driven by the need to predict agglomeration in industrially spray drying processes. In this context, the student will have the opportunity to take our studies down along a number of potential directions, by developing our experimental work and energy analysis and, if desired, by developing complementary computational (CFD) techniques of droplet collisions.  These directions could include: exploring the non-dimensional space by varying viscosity, surface tension and contact angle (as well as size and collision velocity); extending the work to partially dried-droplets; exploring the influence of rotating particles and/or non-spherical particles; understanding the impact of non-Newtonian behaviour; or exploring ternary collisions where unexplained behaviour has been observed.  These droplet scale results and models will then be used in process scale models of industrial test cases to predict spray dryer performance.</p> <p><strong>Leeds Institute for Fluid Dynamics (LIFD)</strong></p> <p>CDT students will also benefit from membership of the Leeds Institute for Fluid Dynamics (LIFD), a cross-disciplinary research institute bringing together the expertise of over 200 researchers from 12 Schools in 4 Faculties at the University of Leeds. The institute provides a hub to facilitate world-leading research and education in fluid dynamics and to bring interdisciplinary perspectives to complex flow challenges.

You will therefore be expected to have broad interests and be willing to learn beyond your core expertise. There will also be the expectation that you will spend an extended period working with either an industrial, environmental or external academic partner as part of your project.</p> <p>You will be part of a cohort of research students with different academic backgrounds, all focusing on different aspects of fluid dynamics. During the selection process we will be looking for students who will be enthusiastic about learning with and from their peers, as well as the ability to undertake their own in-depth research.</p> <p>In the CDT, you will gain key technical and transferable skills for a successful career in industry or academia. Alongside computational, modelling, and experimental methods, you will also develop teamwork, communication, and problem-solving abilities.</p> <p>The major research areas are encompassed in eight cross-disciplinary themes:</p> <ul> <li>Advanced Manufacturing</li> <li>Astrophysics and Geophysics</li> <li>Buildings & Cities</li> <li>Clean Energy</li> <li>Climate & Weather</li> <li>Environmental Flows</li> <li>Health</li> <li>Transport</li> </ul> <p>Future Fluid Dynamics is a crucial discipline for the UK and globally, with significant applications across diverse industries and research domains. It plays a vital role in addressing contemporary societal challenges. It is essential to delivering the clean energy transition, whether through wind, wave or tidal generation, obtaining energy from fusion, or the transport and combustion of greener fuels and carbon capture and storage. In healthcare, fluid dynamics controls oxygen and nutrient transport in the cardiovascular system, the airborne transmission of pathogens and pollutants, and is integral to microfluidics devices for point-of-care diagnostic testing and personalised care. Fluid dynamics is vital to our understanding and mitigation of climate change, capturing the intricacy of extreme earth and space weather events and quantifying uncertainty in environmental flows.</p> <p>Watch our <a href="https://mymedia.leeds.ac.uk/Mediasite/Play/29394cbd82da4021927e59987f2bd2f61d">recorded webinar</a> - meet the Programme Director and learn more about the programme.</p> <p>The programme is available to study part-time or full-time.
