<p>At least one fluid medium is passed in uniflow relation through one or more filler elements comprising layers which contact one another and bound flow channels, the longitudinal axes of the flow channels in each layer extending substantially parallel to one another at least in groups, the longitudinal axes of the flow channels in adjacent layers being inclined relatively to one another, the flow channels of at least any two adjacent layers being at least partly open towards one another.</p> |
