In this project, students will investigate a commercial inkjet printing system: experimental testing will consist of flow visualization using high speed cameras numerical simulations will be performed using the open-source code OpenFOAM. This causes the ink to flash boil, and the bubble thus formed forces the ink through a nozzle, forming a droplet. Thermal inkjet printers generate droplets by rapidly raising the temperature of a thin metallic film adjacent to a supply of ink. Experimental and numerical investigations of thermal inkjet droplet ejection fluid flow plus heat) in one or more simple situations of industrial relevance, for example, flow over a heated block in a channel (mimicking electronic cooling) and flow over aīackward facing step with downstream heated wall (which is a proxy for flow in an inkjet printhead).Ĥ. In this project, the student will use simulation codes to model the conjugate heat transfer (ie. In this project, the student will investigate the fluid mechanics of droplet deposition using CFD simulations.Ĭooling of hot components by fluid flow is widely used in a number of industries. Simulating droplet deposition for 3D printingģD printing (aka additive manufacturing) holds great promise for rapid prototyping and component manufacture. This project has a number of aspects: literature review of biological (eg dental) aerosol size and velocity distribution numerical simulation of generic particle-laden jets, including generic particle extraction methods (what kinds of extraction is required for given ranges of aerosol size and velocity distributions?) experimental testing of aerosol generator: characterizing size and velocity distribution design of aerosol extraction unit for attachment to dental drillsĢ. When operating on at-risk patients human sneezing can increase the spread of viruses. For example: in inkjet printing, stray aerosols can accumulate on machine internals and drip, resulting in print defects dental operations produce highly mobile aerosols which make sophisticated personal protective equipment necessary Many industrial, medical and biological processes produce highly mobile aerosols which can have deleterious effects. He can propose the following topics for thesis and HDR students: He is also an experienced user of the ANSYS suite of tools. He has significant expertise in computational modelling, an in particular, use of open source computer-aided engineering tools, such as OpenFOAM, FreeCAD, Gmsh, FreeFem++, SurfaceEvolver paraview and python.
