The project presents the conceptual design of plume generation and detection systems for ground experiments with sensing robots. The plume generation system provides controlled carbon dioxide concentration profiles and consists of a pressurized tank, a pressure regulator, a flow meter, and a nozzle placed on a stand. The carbon dioxide plume is modeled with the 3d advection diffusion equation and numerical simulations provide the required release rates at the nozzle exit. Nozzle dimensions are estimated using 1d isentropic nozzle theory. The plume detection system consists of three carbon dioxide sensors placed on a horizontal arm that can be repositioned vertically on a stand. Structural analysis is performed for the plume generation and detection stands in order to minimum deflections.
