TY - JOUR TI - Fractional model for heat conduction in polar bear hairs AU - Wang Qing-li AU - He Ji-Huan AU - Li Zheng-Biao JN - Thermal Science PY - 2012 VL - 16 IS - 2 SP - 339 EP - 342 PT - Article AB - Time-fractional differential equations can accurately describe heat conduction in fractal media, such as wool fibers, goose down and polar bear hair. The fractional complex transform is used to convert time-fractional heat conduction equations with the modified Riemann-Liouville derivative into ordinary differential equations, and exact solutions can be easily obtained. The solution process is straightforward and concise.
