About the interaction of charged spheroidal particles in an electrolyte solution

Electrostatic interaction of two charged spheroidal macroparticles in an aqueous solution of a symmetric electrolyte is analyzed within the linearized Poisson-Boltzmann model under the condition of a constant charge on their surfaces.It is assumed that the particles have a common axis of symmetry. Interparticle forces are calculated through finite-element method in the regimes of weak and moderate screening in the absence of external field.
