Evolution of the CR grammage (right part) and residence time (left part) in Setup 1: WNM-CNM and Setup 2: WNM-CNM-DiM represented by a solid curve and a dashed curve, respectively. These setups are compared with the case of the expansion of a CRC in a homogeneous WNM represented by the dotted lines. Each setup phase configuration is represented by a color code: WNM (green), CNM (orange), and DiM (red).
