Abstract: The colliding-jet nozzle which includes a nozzle body portion having a proximal end, a distal end and a fluid inlet defined partially therethrough. The body portion also includes first and second outlet ports disposed through the nozzle body portion for directing fluid from the inlet outwardly therefrom. A proximal end of a first hollow tube is attached and in fluid communication with the first outlet port and a distal end of the first hollow tube extends outwardly therefrom. A first end of a second hollow tube is attached and in fluid communication with the second outlet port and a second end of the second hollow tube is axially aligned with the distal end of the first hollow tube to define a gap therebetween such that fluid exiting from the first outlet port and fluid exiting from the second outlet port directly collide with each other to atomize fluid.
