Argon, nitrogen, air and carbon dioxide/nitrogen mixture (corresponding to Martian atmosphere) were chosen for the study. Modelling the problem of discharge chamber flow was based on mutual consideration of Navier ‒ Stokes and Maxwell equations at given mass flow rates (G = 5 ÷ 30 g/s) over pressure range of р = 10 ÷ 200 mbar and delivered power (energy supply) of N = 50 ÷ 300 kWt. Values of parameters at the discharge chamber exit (Fig. 1) were used then for computation of flow in the work chamber and around test models and probes (Fig. 2). Gas mixture models accounting for nonequilibrium thermochemical processes were utilized under solution of the problems. Developed soft ware is used for both plasma flow diagnostics and interpretation of tests on heat transfer, specification of thermal stability and catalicity of heat shield materials.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114427951","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}

A minimum mechanism describing the combustion kinetics of hydrogen is determined; the mechanism was used to solve an inverse task of finding parameters describing the experimental data of Kowalski at pressures of 7.4, 7.1, 6.8, 6.4 and 6.1 mm Hg. All obtained constants of direct and inverse reactions are interrelated by thermodynamic equilibrium constants. The parameters obtained for the maximum hydrogen combustion mechanism make it possible to describe well the ignition limits in Lewis and Egerton experiments. In carrying out further thermodynamic analysis, a minimal mechanism M-I is identified that corresponds to the maximum mechanism and with good accuracy describing the critical conditions of hydrogen combustion in the pressure interval 1 ÷ 200 mm Hg and temperatures of 400°C ÷ 600 °C. From the analysis of critical conditions, an analytical equation is obtained; roots of the equation give ignition limits close to the experimental ones.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127963749","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}
