Heat transfer in solid parahydrogen and possibility of observing a Poiseuille flow of phonons
Zholonko N. N., Gorodilov B. Ya., Krivchikov A. I.
The thermal conductivity of solid parahydrogen has been measured over the temperature interval 1.5-8 K. The temperature dependence of the thermal conductivity and the size of the effective mean free path of the phonons indicate that a Poiseuille flow of phonons can be observed in solid parahydrogen.
