耗散流体冻结时的熵产生

Entropy production at freeze-out from dissipative fluids

E. Molnar

摘要:

由于剪切粘度在连续冻结出的纵向膨胀耗散流体的熵产生的解决。假设流体动力学描述的有效性,在相互作用的物质的连续去除过程中,我们估计了一个小的熵产生的冻结持续时间的函数和耗散量与非耗散量的比率的情况下,相对论无质量的π介子流体。

英文摘要:

Entropy production due to shear viscosity during the continuous freeze-out of a longitudinally expanding dissipative fluid is addressed. Assuming the validity of the fluid dynamical description during the continuous removal of interacting matter we estimated a small entropy production as function of the freeze-out duration and the ratio of dissipative to non-dissipative quantities in case of a relativistic massless pion fluid.
