Design and Optimization of Compressor for a Fuel Cell System on a Commercial Truck under Real Driving Conditions by Dr Luying Zhang on Wednesday, 17th May 2023 at 10:30 am (BST)
This paper presents a novel methodology, that uses a system-level simulation platform to create a complete vehicle model and simulate the performance of a fuel-cell-powered truck in order to obtain the key fuel-cell compressor operating points together with the resulting residence time spent on each point based on real driving conditions. The key compressor operating points are then fed into a meanline compressor design optimization code which uses a map prediction model for a range of compressor speeds, impeller diameters, hub diameters and axial length ratios to find the optimum settings that meet the same weighting factor obtained from real driving conditions. This initial flow path and design conditions obtained from the meanline design optimization are then used by a 3D Inverse design method to generate an initial 3D impeller geometry. Automatic optimization is then used to optimize the impeller geometry. The casing is also designed by using a unique inverse design method, and the performance of the resulting stage is computed by using a 3D CFD simulation package. The resulting full-stage compressor map is then fed into the system-level model, and the impact of the new design on energy consumption over the actual real-life driving scenario is assessed and analysed. The methodology highlights the importance of rigorous simulation as a means for improving component performance and system efficiency while reducing time-to-market and, thus, development costs.
A 3D inverse design based-rapid multi-disciplinary optimization strategy for radial-inflow turbines by Dr Jiangnan Zhang on Wednesday, 17th May 2023 at 11:50 am (BST)
In this paper, we proposed to use some aerodynamic and mechanical performance parameters from the inverse design solution and a direct optimisation approach to perform the multidisciplinary optimisation. The final optimized design shows similar aerodynamic and mechanical performance as the baseline design (optimized through DOE) with a significantly reduced number of CFD/FEA simulations.
