摘要: The charging process of hydrogen storage tank based on bed activated carbon in a steel container at room temperature (295 K) and medium pressure (10 MPa) is simulated with an axisymmetric geometry model using the finite volume commercial solver Fluent. mass flux profile entrance established user-defined functions (UDFs). heat transfer processes cylindrical packed are discussed considering influence viscous resistance inertial porous media. velocity distribution its effect analyzed. effects flow rate inlet adsorption factor studied. A computational fluid dynamics (CFD) approach simulations used. Results show that near bottom higher than entrance, center wall rises somewhat faster along axial compared to radial direction. highest absolute occurs tank. good agreement found between simulation results available experimental data. maximum magnitude much component, resulting more energy direction In addition, reaches equilibrium earlier when higher, value faster.
