Abstract:In the paper,a fog machine of mixing medicine with double jet pump is put forward.It makes use of air compressor to produce constringent air,makes use of jet pump to mix water with medicine and makes use of jet boat to mix constringent air with water and medicine,arriving at the aim that the medicine and water are mixed equally with constringent air.On jet pump design theory and hydrodynamics basic law,the calculation formula of hydrodynamics parameter is established,and the practicability above mentioned theories is checked with the calculated example of numerical value.
Keywords:hydrodynamics  jet pump  fog machine
