Nozzle flow separation Calculator

The formula for calculating nozzle flow separation depends on the specific characteristics of the flow and the geometry of the nozzle. However, a common approach to modeling flow separation in nozzles is to use the Reynolds number (Re) and the Mach number (Ma) at the nozzle exit.

Where:

  • is the critical Reynolds number for flow separation.
  • is the density of the fluid.
  • is the velocity of the fluid at the nozzle exit.
  • is the characteristic length of the nozzle (e.g., diameter for a cylindrical nozzle).
  • is the dynamic viscosity of the fluid.
