The supersonic gas jets from conical nozzles are simulated using 2D model. The on-axis atom number density in gas jet is investigated in detail by comparing the simulated densities with the idealized densities of straight streamline model in scaling laws. It is found that the density is generally lower than the idealized one and the deviation between them is mainly dependent on the op... https://www.lightemupsequences.com/limited-deal-Women-s-ADU-RipStop-EMT-Pants-special-find/
