A kinetic model for chemical reactions without barriers : transport coefficient...
Alves, Giselle M.; Marques Júnior, Wilson; Soares, A. J.; Kremer, Gilberto M.The kinetic model of the Boltzmann equation proposed in the work of Kremer and Soares 2009 for a binary mixture undergoing chemical reactions of symmetric type which occur without activation energy is revisited here, with the aim of investigating in detail the transport properties of the reactive mixture and the influence of the reaction process on the transport coefficients. Accordingly, the non-equilibrium so...
Transport properties of a kinetic model for chemical reactions without barriers
Alves, Giselle M.; Kremer, Gilberto M.; Soares, A. J.A kinetic model of the Boltzmann equation for chemical reactions without energy barrier is considered here with the aim of evaluating the reaction rate and characterizing the transport coefficient of shear viscosity for the reactive system. The Chapman-Enskog solution of the Boltzmann equation is used to compute the chemical reaction effects, in a flow regime for which the reaction process is close to the final...
Ondas superficiais de gravidade
Fernandes,Alcione S.; Alves,Giselle M.Neste artigo discutimos a propagação de ondas de pequena amplitude num líquido de profundidade constante com base em uma equação de ondas. A solução geral mostra que a velocidade de propagação é dependente do comprimento de onda de modo que ocorre o fenômeno da dispersão. Soluções para os casos de pequena e grande profundidades são também obtidas.
