Abstract

A new numerical model has been introduced to study steady oscillatory heat and mass transfer in the tube section of a pulse-tube refrigerator. Conservation equations describing compressible gas flow in the tube are solved numerically, using high resolution schemes. The equation of conservation of momentum is neglected because the pressure is justified to be uniform in space. The model reduces to solving the equations of conservation of mass and energy. Using our numerical model, we can study the temperature dynamics in the pulse tube, calculate the average enthalpy flow and estimate the refrigeration power.
