Abstract:
To reveal heat transfer mechanism of metal hydride hydrogen storage reactor (MHHSR) efficiently and accurately. Meyer wavelet finite element model (MWFEM) is built integrating MWSF to conventional finite element model, which can effectively implement heat transfer analysis of MHHSR. Firstly, heat transfer models of MHHSR is established, which contains governing equations of metal hydride bed, governing equations of heat exchange fluid, and corresponding heat transfer boundary conditions. Secondly, MWSF is considered as interpolation function to build MWFEM. Finally, MgH2 reactor is selected as object to conduct heat transfer analysis, effect of hydrogen supply pressure, heat exchange fluid temperature, heat exchange fluid velocity and porosity on heat transfer law of MgH2 reactor are achieved by proposed MWFEM, conventional finite element model, B-spline wavelet finite element model, Daubechies wavelet finite element model and experiment. Heat transfer mechanism of MgH2 reactor is acquired, results offer significant basis for optimal design of MgH2 reactor, accuracy and efficient of proposed MWFEM are validated.
