Abstract
Abstract A contact body for the direct transfer of heat and/or substances between a liquid medium and a gaseous medium composed of adjoining cross-wise oriented, undulated flow panels, shaped into parallel equidistantly spaced troughs with undulation bottoms and undulation ridges truncated at two levels at regular intervals to reduce the number of contact points between adjoining flow panels, thereby reducing the pressure drop in the transverse flow of the gaseous medium.
