N2 - Research on the drag-reducing structure of the haploid interval riblets surface is carried out with the numerical simulation, and in view of its flow field features, this paper appropriately deals with the computing domain, grids and flow parameters during the numerical calculation. By the adoption of iSIGHT software, structure parameters generated program of riblets surface, hydrodynamic numerical simulation software GAMBIT and FLUENT is integrated. With optimized design technology and the numerical simulation technology, the optimization design of the bottom angle on the riblets surface is made by adopting the two-stage combining optimization method which includes overall search based on adaptive simulated annealing algorithm and partial optimal search of sequential quadratic programming. The results show that after the optimization design, the relative amount of drag reduction of the riblets surface reaches 3.506 %. Compared with the initial value, the relative amount of drag reduction increases and the drag-reducing effect is remarkable. This provides a new direction for the research on drag reduction of riblets surface.
