This engineering thermo-fluids PhD studentship is related to an EPSRC-funded project, EP/V02695X/1 Better Bubblers: Jet Impingement within a Dead-End Channel.
In the high pressure aluminium die casting (HPADC) and injection moulding (IM) industries, a unique flow field is used to cool slender mould protrusions: a jet impingement confined within a dead-end channel, known in industry as a 'bubbler'. These devices are used ubiquitously, however their implementation within a mould has been constrained by the limitations of 2D machining; recent advances in Additive Manufacturing (AM) now offer timely and novel opportunities to improve their design. Our challenge is that the heat- and flow-regime associated with a bubbler has received limited attention in the literature, so an improved understanding is required to access the optimum cooling performance that the AM of these devices can enable.
The goal of this project is therefore to establish the heat and flow phenomenology associated with bubblers, and to develop novel methods that will enable their design to be optimised for AM. The successful candidate will be working with an industrial partner, and will be involved in experimental work (i.e. in designing, commissioning, and collecting experimental fluid mechanics and heat transfer data), highly-resolved computational fluid dynamics simulations (e.g. Large Eddy Simulation) and adjoint optimisation methods.
