What process is described as bouncing water off the inside wall of the nozzle bore to create a fog pattern?

The process described as bouncing water off the inside wall of the nozzle bore to create a fog pattern is referred to as periphery deflection. This technique involves altering the trajectory of water flow within the nozzle, allowing the water to collide with the inner surface and split into smaller droplets, which ultimately creates a fog pattern. This method is advantageous in firefighting, as the fog can help absorb heat and reduce visibility, making it an effective tactic for controlling fire spread and protecting firefighters.

Other terms in the options relate to various aspects of water application techniques, but none describe the specific interaction of water with the nozzle's interior to produce a fog pattern as accurately as periphery deflection does.
