The inertance type pulse tube cryocooler has accumulated applications in various fields such as aerospace, bio-tech and military by achieving temperatures below 100 K. The computational fluid dynamics approach chosen for the present work deals with the complex, confined and cyclic fluid flows encountered in the cryocooler. The analysis of the cryocooler for the zero-refrigeration load condition is carried out using the Ansys Fluent® software. A parametric study of the cryocooler is conducted by varying the pulse tube radius and reservoir volume, where an increase in cooling performance is observed. Porous medium of regenerator was also varied which emanated a fluctuating cooling performance for the range of porosity.
