[en] A MATHEMATICAL MODEL FOR A CONVECTIVE HEAT TRANSFER PROCESS / [pt] MODELO MATEMÁTICO DE UM PROCESSO CONVECTIVO DE TRANSFERÊNCIA DE CALOR

JOSE MARIA GARCIA CASELLES 04 August 2008 (has links)
[pt] Este trabalho visa a modelagem de um processo convectivo de transferência de calor entre vapor de água e óleo. Estudam-se as diversas possibilidades de solução do sistema de equações diferenciais a derivadas parciais com coeficientes variáveis com o tempo, concluindo-se que o método de discretização no espaço é o de maior eficácia no caso presente. Uma vez obtido o modelo teórico aplica-se o método do modelo para a identificação dos parâmetros mediante técnicas de simulação no CSMP do computador IBM-1130. / [en] This work is concerned with the modeling of a convective heat transfer process between steam and oil. By studying the different ways of solution of two simultaneous partial differential equations with time dependent parameters, it is concluded that to lump the equations with respect to the spacial coordinates is the most useful method in the present exemple. Once the theoretical model is obtained, the model method is used to identify the parameters with the CSMP in the IBM-1130 computer.
