                         foguete a propelente l{\'{\i}}quido (MFPL). Inicialmente foi 
                         escolhida uma geometria como caso padr{\~a}o e realizado o 
                         c{\'a}lculo semi-emp{\'{\i}}rico. Esta etapa teve como objetivo 
                         determinar as condi{\c{c}}{\~o}es de contorno de fluxo de calor 
                         proveniente da combust{\~a}o. Posteriormente, a geometria e a 
                         malha foram modeladas em software param{\'e}trico e ent{\~a}o 
                         analisada a transfer{\^e}ncia de calor conjugada por

                         software OpenFOAM. A partir de uma modelagem por CFD funcional, 
                         programou-se o ciclo de otimiza{\c{c}}{\~a}o. Os par{\^a}metros 
                         geom{\'e}tricos da jaqueta de refrigera{\c{c}}{\~a}o foram 
                         variados, atrav{\'e}s de um algoritmo, at{\'e} se encontrar o 
                         ponto {\'o}timo. Os objetivos da otimiza{\c{c}}{\~a}o foram, 
                         diminuir as temperaturas nas paredes e perda de carga, levando-se 
                         em considera{\c{c}}{\~a}o os crit{\'e}rios restritivos

                         Os resultados permitiram obter uma jaqueta de

                         work presents a study of optimization of typical cooling jacket 
                         for liquid propellant rocket engine (LPRE). Initially a geometry 
                         was chosen as the standard case and the semi-empirical calculation 
                         was performed. The purpose of this step was determine the heat 
                         flux boundary conditions provide by combustion. Posteriorly, the 
                         geometry and mesh were design on parametric software and then 
                         analyzed the conjugated heat transfer by computational fluid 
                         dynamics (CFD) in OpenFOAM software. From a functional CFD 
                         modeling, the optimization cycle was programmed. The geometric 
                         parameters of the cooling jacket were varied, through an 
                         algorithm, until the optimum point was reached. The objectives of 
                         the optimization were reduce the temperatures on the walls and 
                         pressure loss, taking into account the structural criteria and the 
                         maximum temperature of the fuel. The results allowed to obtain a 
                         cooling jacket optimized and a tool of analysis of cooling systems 
                         for liquid propellant rocket engine.",
