| Description | 1. First demonstration of optimised 3D printed heat exchangers to be applied to acoustic engines. Initial designs printed in polymeric materials. Designs currently being developed for printing with minimal support systems with our collaborators Renishaw. 2. Complex single element heat exchangers components have been designed and printed and XCT quality assurance has been carried out in terms of geometry requirement (Dec/Jan 2020). 3. Further designs for exemplar regenerator parts have been completed and printed. The design called for the printing of lattice structures with varying levels of porosity and lattice beam thickness. The parts are currently undergoing a series of X-ray Computer Tomography assessments to examine thier build consistency (Feb/Mar 2020). Following this assessment full mesh replacement parts can be printed and their efficacy verified. 4.In the, a new technique for designing surface texture on the CAD of lattices has been investigated and correlated with areal surface roughness parameters. After extracting areal surface parameters from the XCT data of the lattice, the method allowed for the design of this surface texture on the part CAD taking in consideration if its up skin or down skin, without using XCT data as the main input. By applying this method, it is possible to obtain a lattice CAD model with a designed surface texture and geometry that is more representative of the actual AM lattice. The mean deviation between the CAD model with the designed surface and the XCT was a third of the one between the XCT and the initial CAD. The proposed method allows for designing and replicating LPBF AM surfaces on the CAD of a lattice, taking into consideration the dimensional deviation caused by AM surfaces, especially on overhangs. Assuming that an LPBF AM process is stable and produces approximately the same AM surface, this method can be used to predict the geometry of a lattice, providing a cost-effective and efficient methodology that minimizes the time needed for design validation. |
| Exploitation Route | 1. The basic principles developed here could be applied in several designs for acoustic engines and other heat exchangers for automotive and power applications 2. Design concepts completed could be applied to complex filter systems where single unit complex geometry filters are required |
