Embodiment 1
[0042] For a certain type of engine vortex, the material is K536, such as Figure 1-3 Shown, adopt the present invention to carry out the method for verification of theoretical air flow as follows:
[0043] (1) Modeling of vortex generator: use UG for theoretical size modeling
[0044] (2) Determination of the model runner range:
[0045] In this embodiment, a computer is used to construct a theoretical model of flow rate based on dimensional tolerances on the flow channel model of the three-dimensional digital model;
[0046] Maximum flow model: the maximum difference in the height of the flow channel, the minimum value of the blade thickness and the radius of the intake and exhaust.
[0047] The minimum flow model: the minimum height of the flow channel, the maximum blade thickness, and the maximum radius of the intake and exhaust.
[0048] (3) Split the vortex into two parts along the radial section of the part at the position of the flow channel for additive and subtrac...
Embodiment 2
[0056] A certain type of engine has a vortex with a venturi tube, the material is K536, and the method of the present invention is used to verify the theoretical air flow of the vortex. The specific method is as follows:
[0057] (1) Modeling of the vortex: UG is used to model the theoretical size. For the convenience of modeling, the Venturi structure is removed.
[0058] (2) Determination of the range of the flow path of the model: use the computer to construct the theoretical model of the flow rate, the maximum flow model, and the minimum flow model according to the dimensional tolerances on the flow channel model of the three-dimensional digital model.
[0059] Maximum flow model: the maximum difference in the height of the flow channel, the minimum value of the blade thickness and the radius of the intake and exhaust.
[0060] The minimum flow model: the minimum height of the flow channel, the maximum blade thickness, and the maximum radius of the intake and exhaust.
