Résumé

A dynamic experimental apparatus was designed and constructed to investigate oscillating flow characteristics in a regenerator subjected to a periodically reversing flow established by means of a self-made linear compressor. Detailed experimental data of oscillating pressure drops and phase shift characteristics for regenerators in a high frequency pulse tube cryocooler with an operating frequency of 50 hertz were given. The correlation equations for the maximum and cycle-average friction factors in terms of Reynolds number and dimensionless distance X were obtained.
