A nozzle for generating from a fluid and a gas an aerosol comprising fluid particles, the nozzle comprising: an aerosol exit orifice extending to an outer nozzle surface of the nozzle, wherein the aerosol exit orifice has an aerosol exit orifice diameter, a central axis and has a circumferential edge from which an aerosol exit channel of the nozzle extends from the outer nozzle surface toward an aerosolizing space within the nozzle connecting the aerosolizing space with the outer nozzle surface; a fluid supply channel with a fluid exit orifice that is aligned on the same central axis as the aerosol exit orifice and opens into the aerosolizing space within the nozzle at a distance from an entrance from the aerosolizing space to the aerosol exit channel, the aerosol exit orifice diameter being at least 1.3 times larger than a fluid exit orifice diameter; a converging annular pressurized gas channel extending at an acute gas flow angle with respect to the central axis, said converging annular pressurized gas channel having a pressurized gas exit at the fluid exit orifice so that pressurized gas exiting through the pressurized gas exit intersects with fluid exiting from the fluid exit orifice; wherein the converging annular pressurized gas channel extends between a cone-shaped fluid supply nozzle insert of the nozzle, said cone-shaped fluid supply nozzle insert having a conical wall, and a front insert of the nozzle, said front insert having an inner front insert wall, wherein said converging annular pressurized gas channel comprises a first partial annular channel and a second partial annular channel, the first partial annular channel having inner and outer walls formed by the conical wall and the inner front insert wall along which the pressurized gas flows with the acute gas flow angle being defined by a conical wall angle as measured between the conical wall and the central axis and a front insert wall angle as measured between inner front insert wall and the central axis at the fluid exit orifice, wherein the acute gas flow angle is the sum of the conical wall angle and the front insert wall angle divided by two; the fluid supply channel is provided within the cone-shaped fluid supply nozzle insert forming the conical wall that is the inner wall of the first partial annular channel, designed as a converging circumferential compressed gas channel that is axially centered in a cone-shaped hollow space of the front insert forming the inner front insert wall that is the outer wall of the first partial annular channel; characterized in that the acute gas flow angle is between 10 and 30°; and the distance between the fluid exit orifice and the entrance to the aerosol exit channel is greater than twice the fluid exit orifice diameter and within a range between 100 μm and 2 mm. an aerosol exit orifice extending to an outer nozzle surface of the nozzle, wherein the aerosol exit orifice has an aerosol exit orifice diameter, a central axis and has a circumferential edge from which an aerosol exit channel of the nozzle extends from the outer nozzle surface toward an aerosolizing space within the nozzle connecting the aerosolizing space with the outer nozzle surface;
