DC flow was found to exist in most double-inlet pulse tube coolers from theoretical simulations. DC flow effects in a 4 K pulse tube cooler were studied by numerical analysis and experiment. Numerical predictions show that a negative DC flow from the hot end of the pulse tube to the inlet of regener
