The governing system of equations includes the Navier ‒ Stokes equations for the gas phase and the thermoelasticity equations using the Duhamel ‒ Neumann relations. The equations of conservation of mass and heat balance of the gas phase contain tensors of mass and thermal dispersion, conductive and convective transfer. The results of studying the effect of thermal and concentration expansion on variable porosity in the process of synthesis of micron barium titanate powders during carbon combustion are presented. A dimensionless form of the constitutive equations with similarity parameters is given. Dimensionless equations are applied to the nu-merical simulation of the effect of thermal and mass dispersion at variable porosity on the synthesis of micron barium titanate particles in a three-zone reactor. The results of calculations, including the effect of dispersion, pore tortuosity coefficient, particle diameter, local values of Peclet numbers are presented. The proposed model makes it possible to analyze and evaluate the effect of thermal and concentration expansion on the velocity of the combustion and synthesis front, as well as on the uniformity of the distribution of the reactants and the synthesis product in the reactor.","PeriodicalId":309290,"journal":{"name":"Physical-Chemical Kinetics in Gas Dynamics","volume":"21 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":"130607904","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}

Test calculations were performed for meteor bodies of various sizes moving in the atmosphere. Change of the trajectory angle with respect to the horizon depending on the entry parameters is shown.

Simulations are performed for the conditions of experiments performed in the IGP-4 plasmatron available in IPMech RAS for four operating powers and three test materials with known catalytic recombination coefficients. The computational model describes two-dimensional flow of chemically non-equilibrium nitrogen plasma. Stefan − Maxwell equations are applied to model multicomponent diffusion in the flow and on the catalytic surface. Reasonable agreement between the calculated and measured heat fluxes is demonstrated. It is shown that deviation of the results of the computational model from the ex-perimentally determined heat fluxes is generally within 15 % (the highest deviation is 29 %). Possible reasons for the deviation are discussed, and the dependence of heat fluxes on the kinetic scheme is demonstrated.","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":"127338119","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}
