The multi-component fluid closure derived by Zhdanov [1] is implemented in the fluid code SOLEDGE3X-EIRENE to deal with arbitrary edge plasma composition. The closure assumes no distinction in between species such as light vs heavy species separation. The work of Zhdanov is rewritten in a matricial form in order to clearly link friction forces and heat fluxes to the deifferent species velocities and temperature gradients.
