description: The subject of the graduate qualification work is âNumerical simulation of the vortex flow structure generated in supersonic flow past the finâbody interaction region with modified geometryâ. The given work is devoted to the numerical study of the flow structure features and the picture of local heat transfer in supersonic flow past the finâbody interaction region and evaluation of the effectiveness of reducing thermal loads on the streamlined surface due to the complexity of the geometry of the considered configuration.Research objectives: Review of the articles devoted to the problem of supersonic flow past the finâbody interaction region, in which the influence of geometric parameters on the flow structure and heat transfer is investigated. Carrying out calculations for the basic geometry (in the finâbody interaction region with a right angle); methodical study of the influence of the computational domain size and the position of the boundaries on solution; Carrying out calculations for the modified geometry obtained using fillet in the finâbody interaction region; Carrying out calculations for the modified geometry obtained using sweep angle of the body; Analysis of the flow structure and the picture of the local heat transfer for considered configurations. The calculations were performed using of the finite-volume âunstructuredâ SINF/Flag-S code developed at PhysMech SPbPU.As a result of considering two variants of the finâbody interaction region with modified geometry (using fillet and sweep angles), it was found that the vortex structure in the front separation region changes in the presence of fillet, the number of vorticities and their sizes decrease with an increase of fillet radius. The number of vorticities remains the same but their sizes decrease with an increase of the sweep angle. The picture of the local heat transfer in the finâbody interaction region is compared. It was shown that an increase of fillet radius allows to reduce the maximum value of the Stanton number on the body surface, but does not lead to a significant decrease in thermal loads on the surface of the streamlined plate. On the contrary, an increase of sweep angle leads to a significant decrease in the pick values of the Stanton number on the plate surface (about 6 times for a sweep angle of 15 degrees), while the picture of the Stanton number distribution on the body surface remains almost the same.
