Poster summary

This poster contains general-purpose analysis and design software with a modern user interface that can help scientists and engineers to build a pulse tube cryocooler of any cooling capacity at any given temperature. The basic design approach in GM-type PTR is based on the trapezoidal profile of pressure vs time curve, the well-known isothermal model inside the pulse tube, heat transfer in the regenerator considering both primary (convection) and secondary (axial conduction) effects. The thermal and pneumatic descriptions are based on exergy analysis. Most relevant loss mechanisms such as regenerator convective losses (thermal and pneumatic), axial conduction, and mixing in pulse tubes have been taken into account. The software is written in MATLAB, has a decent graphical user interface, and assists the designer not only in feeding input information but also in generating reports.
