The CFD Fluent software is used to numerically simulate the whole working process of the needleless injector, and the law of the change of the driving pressure of the liquid medicine and the liquid jet velocity in the injection tube is obtained.

The CFD Fluent software is used to numerically simulate the whole working process of the needleless injector, and the law of the change of the driving pressure of the liquid medicine and the liquid jet velocity in the injection tube is obtained. The evolution process of medicinal liquid jet in the air is simulated, and the whole process of jet penetrating the skin and spreading in the skin layer and subcutaneous tissue layer is simulated. The numerical results are consistent with the experimental qualitative results.
