A condensation management system comprising: an elongated flexible film configured to be stretched under tension along a longitudinal axis of the film between a first film support and a second film support, the film comprising: first and second ends (111, 112) extending laterally across width of the film; first and second sides (113, 114) extending longitudinally between the first and second ends; a concave surface extending between the first and second sides and an opposing convex surface extending between the first and second sides; and microchannels disposed in at least one of the concave surface and the convex surface, the microchannels arranged at an angle greater than zero with respect to the longitudinal axis of the film and configured to induce a predetermined radius of curvature in the concave and convex surfaces of the film when the film is stretched longitudinally between the first and second film supports, wherein the predetermined radius of curvature is a function of a distance between the first and second supports, each of the first and second film supports has a substantially flat attachment surface to which the first and second ends of the flexible film are respectively attached, a minimum value of the radius of curvature of the film occurs at a longitudinal intermediate point of the film between the first and second film supports and a maximum value of the radius of curvature occurs proximate to the first and second film supports. an elongated flexible film configured to be stretched under tension along a longitudinal axis of the film between a first film support and a second film support, the film comprising: first and second ends (111, 112) extending laterally across width of the film; first and second sides (113, 114) extending longitudinally between the first and second ends; a concave surface extending between the first and second sides and an opposing convex surface extending between the first and second sides; and first and second ends (111, 112) extending laterally across width of the film; first and second sides (113, 114) extending longitudinally between the first and second ends; a concave surface extending between the first and second sides and an opposing convex surface extending between the first and second sides; and microchannels disposed in at least one of the concave surface and the convex surface, the microchannels arranged at an angle greater than zero with respect to the longitudinal axis of the film and configured to induce a predetermined radius of curvature in the concave and convex surfaces of the film when the film is stretched longitudinally between the first and second film supports, wherein the predetermined radius of curvature is a function of a distance between the first and second supports, each of the first and second film supports has a substantially flat attachment surface to which the first and second ends of the flexible film are respectively attached, a minimum value of the radius of curvature of the film occurs at a longitudinal intermediate point of the film between the first and second film supports and a maximum value of the radius of curvature occurs proximate to the first and second film supports.
