Résumé

Heat removal in the orifice pulse-tube is analyzed using a thermodynamic model. The cycle considered has four distinct steps: 1) the pressure is increased "compression"; 2) there is leakage through the orifice out of the pulse tube "orifice outflow"; 3) the pressure is decreased "expansion"; 4) there is leakage through the orifice into the pulse tube "orifice inflow". Leakage through the orifice during the compression and expansion steps is neglected. The pressure is assumed to be uniform during the entire cycle.
