A venturi-style vehicle washing system and method of washing a vehicle. The washing system and method produces large droplets of a liquid-gas mixture for washing a vehicle by mixing an energetic flow of gas carried at a first velocity through a gas conduit, with a liquid carried at a second velocity through a liquid conduit. A mixture conduit may carry the liquid-gas mixture to a vena contracta structure where: a jet forms, pressure drops, and velocity increases. The gas leaving the structure may expand to fill an outlet duct, creating turbulent vortexes in the liquid-gas mixture that transforms flowage kinetic energy to heat energy, which decreases pressure through the outlet duct. This results in increasing velocity of the liquid-gas mixture discharged onto the vehicle. The outlet duct operationally attaches to a spray arch that is sized to enable passage of a vehicle for washing with the liquid-gas mixture.
