Numerical Investigation of a 3D Inertance Pulse Tube Refrigerator from Design Prospective

•The computational overhead is the actual reason which may stop many researchers to solve in 3D.•In 3D analysis modelling the appropriate contact of components and meshing are to be analysed.•The complexity is alleviated by implementing user define function in case of 3D simulation.•The numerical error on introducing pressure wave needs to be analysed.
