  We study the dynamics of liquid climbing in a narrow and tilting corner,
inspired by recent work on liquid transportation on the peristome surface of
Nepenthes alata. Considering the balance of gravity, interfacial tension and
viscous force, we derive a partial differential equation for the meniscus
profile, and numerically study the behavior of the solution for various tilting
angle $\beta$. We show that the liquid height $h(t)$ at time $t$ satisfy the
same scaling law found for vertical corner, i.e., $h(t) \propto t^{1/3}$ for
large $t$, but the coefficient depends on the tilting angle $\beta$. The
coefficient can be calculated approximately by Onsager principle, and the
result agrees well with that obtained by numerical calculation. Our model can
be applied for a weakly curved corner and may provide guidance to the design of
biomimetic surfaces for liquid transportation.
