In this concept, the temperature difieerence between an up-stream and a down-stream temperature sensor is kept constant at zero, by controlled distribution of a constant total heating power between an up-stream and a downstream heater.

SIMULATION OF FLUID FLOW WITH INTERACTING PARTICLES

Navier-Stokes equations are introduced for incompressible flows, however locally, whenever a particle appears, the density in this very element decreases, due to the fluid volume displaced by the particle.

Compressible flow
Compressible flow (gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid density. Gases, but not liquids, display such behaviour. To distinguish between compressible and incompressible flow in air, the Mach number (the ratio of the speed of the flow to the speed of sound) must be greater than about 0.3 (since the density change is greater than 5% in that case) before significant compressibility occurs. The study of compressible flow is relevant to high-speed aircraft, jet engines, rocket motors, hyperloops, high-speed entry into a planetary atmosphere, gas pipelines, commercial applications such as abrasive blasting, and many other fields.
