TY - JOUR TI - A fractal derivative model for snow's thermal insulation property AU - Wang Yan AU - Yao Shao-Wen AU - Yang Hong-Wei JN - Thermal Science PY - 2019 VL - 23 IS - 4 SP - 2351 EP - 2354 PT - Article AB - Snow is of porous structure and good thermal insulation property. A fractal derivative model is established to reveal its thermal property, it is extremely high thermal-stable, the whole snow will not be affected much by the sudden environmental temperature change. A simple experiment is carried out to verify the theoretical finding, and the result is helpful to design advanced materials mimicking the snow structure.
