Numerical simulation was carried out in N2 (nitrogen) gas. For numerical simulation, the author's computer codes UST3D-AUSMUP2, UST3D-AUSMPW and USTFEN, developed at IPMech RAS, were used. These computer codes are based on the model of the complete system of Navier-Stokes equations for a perfect gas, which is solved by different methods on an unstructured grid. Validation and verification of the obtained results were carried out. For numerical simulation of the flow, a geometric model of a double cone 25°/55° was constructed.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two features affects the correct comparison opportunity. The first is the virtual and experimental model differences, i.e. the different wetted area. The second is the drag coefficient terms evaluation: pressure drag, skin friction and base drag. The skin friction calculations were performed by the flat plate correlations. The results show that skin friction plays the significant role in the overall drag within the wide Mach number range.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127449170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For a numerical study, experimental data were selected [Burrows M.C., Kurkov A.P.] An analytical and experimental study of supersonic combustion of hydrogen in the vitiated air stream. AIAA J. 1973. No.11. Pp. 1217–1218], which have been used for several decades to validate computer codes and physicochemical models of hydrogen combustion in air. Used computer code NERAT-2D implements the numerical integration of two-dimensional Na-vier − Stokes equations on structured multi-block grids. The problem is solved on a sequence of calculation grids without and using Reynolds averaging. The 8-reaction kinetic Evans − Schexnayder model of combustion of molecular hydrogen in hot humid air was used. It is shown that on relatively coarse computational grids, the calculated limit of ignition of a hydrogen jet in an airflow significantly exceeds that measured in the experiment. On detailed computational grids, an unsteady motion of an ignitable hydrogen jet is observed, and the ignition boundary corresponds with good accuracy to the experimental one. As an appendix to the article, a number of animation files are presented that illustrate the unsteady combustion of a hydrogen jet in a co-currents flow of moist air.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117280617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
