Example 1:
The non-smooth concave-convex structure of Huang Yuanzhen dragon lice front breast back plate surface and surface bristles limits the formation of continuous water film, increases wedge-opening pressure, is favorable for improving the lubrication capacity of interface and reduces resistance in water. In researches, the non-smooth morphological structures such as tortoise-plastron-shaped concave-convex structure are found, firstly, the drag reduction effect in the gas-liquid two-phase flow is facilitated, the gas-liquid separation phenomenon caused by collision between the gas-liquid two-phase flow and the non-smooth morphological structures such as tortoise-plastron-shaped concave-convex structure is weakened, and secondly, the adhesiveness of the gas-liquid two-phase flow, particularly the gas mass, can be reduced.

Specifically, as shown in fig. 2-3, the chord length of the blade 1 is L, the blade height is H, the blade head bionic structure comprises 4 cylindrical grooves 6, the section radius R of each cylindrical groove 6 is 1/30 of the blade height H of the blade 1, the cylindrical grooves 6 are uniformly distributed along the head of the blade 1, and the centers of the cylindrical grooves 6 are offset by 30 degrees.
Further, as shown in fig. 4, the hub bionic structure 5 includes a plurality of conical protrusions, the interval L is 1/10 of the chord length L of the blade 1, the height H is 1/15 of the blade height H of the blade 1, the conical protrusions are uniformly distributed in a trapezoid staggered manner along the position of 2/3L (chord length) of the trailing edge of the blade, and the conical protrusions are distributed in 7 rows in total, wherein the first row has 5 conical protrusions, the second to third rows have 6 conical protrusions, and the fourth to seventh rows have 7 conical protrusions.
The utility model provides a gas-liquid mixing delivery pump impeller with a bionic structure, which has the following working principle: the gas-liquid two-phase flow flows into the impeller runner of the gas-liquid mixing pump through the inlet 8, as shown in fig. 5 and 6, compared with the non-bionic structure smooth impeller head 7 of the traditional mixing pump, the gas-liquid two-phase flow flowing through the bionic structure 3 of the impeller head is converged inside the grooves of the bionic structure to form small reverse vortex, the reverse vortex plays a role of a bearing, the bearing changes sliding friction between the gas-liquid two-phase flow and the surface of a cone into rolling friction, the resistance of the rolling friction is far smaller than that of the sliding friction, the energy loss is favorably reduced, the impact separation of the blade head is also the most important cause of the gas-liquid two-phase separation of the gas-liquid mixing pump, and the gas-liquid separation of the rolling friction formed by the bionic structure is far smaller than that caused by the non-bionic structure smooth impeller head, so that the working performance of the mixing pump is further improved.
