Abstract To study the heat and mass transfer characteristics of alkali metals in a
combined porous wick in high-temperature heat pipes, a three-dimensional (3-D)
numerical model is constructed by using the finite volume method, Darcy’s theory, and
the theory of local thermal equilibrium. The research finds that the pressure drop of
fluids flowing through a combined porous wick exhibits an increasing trend with
increasing flow velocity at the inlet and with decreasing permeability of the porous
media; a combined porous wick of lower porosity and permeability and larger fluid
velocity at the inlet is found to More >
