Abstract
We develop a computational model of quantum turbulence decay employing a kinematic prescription for the normal fluid. We find that after an initial transient, the length of the vortex tangle L decreases and for large times obeys a scaling law with a -0.45 exponent. The average magnitude (along the quantized vortices) of the superfluid and line-vortex velocity are close and differ significantly from the average magnitude of the normal fluid velocity.
