Abstract
A pore model is developed combining discontinuities at the pore wall with continuous streamlines. Through a transformation of coordinates the equation of motion can be solved rigorously while the continuity equation is satisfied. This pore model is called the semisinusoidal pore model. Application of this model to hydrodynamic and electrical transport phenomena shows that the model is in better agreement with the data than models comprising either straight or tortuous circular pores.

Abstract
The semisinusoidal pore model describes the electrokinetic transport correctly when electrical conductance is predominantly bulk conductance. On the basis of irreversible thermodynamics and the semisinusoidal pore model a stability diagram can be constructed showing the conditions under which stationary transport is possible. In describing surface conductance and convective charge transport, differences between model predictions and experimental data exist. It is shown that these differences are related to assumptions concerning the electrical charge distribution rather than to the pore model itself.
