@baklazan najpewniej przepływ płynu (gaz też jest płynem, ale nie cieczą) - to symulacja. I pokazuje gradienty ciśnień. To kluczowe w przypadku tych diamentów, bo to szczyty nakładających się fal stojących wynikających z charakterystyki przepływu. Tutaj masz dokładniej: https://en.wikipedia.org/wiki/Shock_diamond

Shock diamondShock diamonds (also known as Mach diamonds or thrust diamonds, and less commonly Mach disks) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet, or scramjet, when it is operated in an atmosphere. The "diamonds" are actually a complex flow field made visible by abrupt changes in local density and pressure as the exhaust passes through a series of standing shock waves and expansion fans. The physicist Ernst Mach was the first to describe a strong shock perpendicular to the direction of fluid flow, the presence of which causes the diamond pattern. Mechanism Shock diamonds form when the supersonic exhaust from a propelling nozzle is slightly over-expanded, meaning that the static pressure of the gases exiting the nozzle is less than the ambient air pressure.
