Lu, Y., Rane, S. & Kovacevic, A. ORCID: 0000-0002-8732-2242 (2022). Evaluation of cut cell cartesian method for simulation of a hook and claw type hydrogen pump. International Journal of Hydrogen Energy, 47(54), pp. 23006-23018. doi: 10.1016/j.ijhydene.2022.05.110

Abstract

Hook and claw pumps are used for recirculation of excess hydrogen in fuel cells. Optimization of the pump design is essential. Computational Fluid Dynamic (CFD) is an effective method for performance optimization. However, it is difficult to conduct CFD simulation because of the sharp cusp of the rotor profile. Cut cell Cartesian mesh could be the solution to handle this complex and moving geometries. The aim of this paper is to evaluate ANSYS Forte for hook and claw pumps. Firstly, the conservation accuracy of the cut cell cartesian mesh is verified using an adiabatic piston cylinder case. Then, simulation results of hook and claw type pump are compared with experimental data. Finally, simulation results of air and hydrogen are compared. The results show that the CFD simulation of hook and claw pumps using cut cell cartesian mesh could provide an efficient and effective approach for the optimization of the system.
