Example Embodiment
[0081] Example 1.
[0082] In the first embodiment, the two-section structure of the turbine box channel is specifically: a channel structure with a large A / R value and a small A / R value (that is, the first channel section 2 with a large A / R value, and a small A / R value). R value of the channel structure of the second channel segment 4).
[0083] see image 3 As shown, select the original design of two channels (including the first channel segment 2 and the second channel segment 4) with different A / R values, where f 大 (0, A / R) and f 小 The A / R value of the (0, A / R) channel (that is, the channel segment with a large A / R value and the channel segment with a small A / R value) differs by 10-30%;
[0084] For the present invention, see Figure 4 , Figure 5 As shown, the first channel section 2 of the same turbine selects a large A / R value, that is, f 大 (0, A / R) first 135 degree channel design parameter f 大 (θ, A / R), the second channel segment 4 selects a small A / R value, tha...
Example Embodiment
[0088] Example two.
[0089] In the second embodiment, the two-section structure of the turbine box channel is specifically: a channel structure with a small A / R value to a large A / R value (that is, the first channel section 2 with a small A / R value, which is turned to a large A / R value) Channel structure of the second channel segment 4 for the R value).
[0090] see image 3 As shown, select the original design of two channels (including the first channel segment 2 and the second channel segment 4) with different A / R values, where f 大 (0, A / R) and f 小 The A / R value of the (0, A / R) channel (that is, the channel segment with a large A / R value and the channel segment with a small A / R value) differs by 10-30%;
[0091] For the present invention, see Image 6 , Figure 7 As shown, the same first channel section 2 of the turbine selects a small A / R value, that is, f 小 (0, A / R) first 135 degree channel design parameter f 小 (θ, A / R), the second channel segment 4 selects a larg...
