Abstract: A mixer for mixing a fluid solution, such as a diesel exhaust fluid for selective catalytic reduction, with a gas, such as an exhaust gas, includes a mixing chamber with a general cylinder shape obtained by translation of a polarly period section along a first axis. The fluid solution is sprayed in the mixing chamber by way of a first axial end thereof. The gas enters the mixing chamber through openings formed in a generatrix surface of said mixing chamber, and the mixture exits through a second axial end opposite the first axial end. The polarly period section is shaped in a star, obtained by polarly periodically repeating an elementary profile, comprising an opening defined by a first angle between a first segment passing through the two ends of said opening and a radial line passing through the distal end of said first segment.
