Aiming the decrease of manufacturing costs, the automotive industry uses Computational Aided Engineering (CAE) and prototype testing for product development. In the field of simulation CAE could be performed using FEA (finite element analysis) or CFD (Computational Fluid Dynamic), the last one is the analysis of systems involving fluid flow, heat transfer and associated phenomena such as chemical reactions by means of computer-based simulation. One of the most important components of cooling system is a water pump which is evaluated through the fluid dynamic analysis. Therefore, this work aims to analyze the fluid flow inside an automotive water pump considering a three-dimensional steady-state using CFD, but also developing a methodology to evaluate it. The parameters of the analysis and the volumetric mesh were according to the simulated results approached the experimental results.

This paper aims at analytical and numerical evaluation of the structure of a Baja. It will be described some load conditions to analyze the overall structure of Baja well as localized elements, in order to prevent premature failure of the vehicle during the competition and improvements in the design phase. The numerical analysis will be conducted via finite elements to establish the optimization of weight and gain performance of the vehicle. Analytical evaluation it will conducted via propositions of physics. Results obtained for the initial concept of the project and compared with the structural changes after the trial proposition will be presented. Analysis of study resulted in improvements in manufacturing reducing weight. Also it was expected to increase the structural performance associated to a better understanding of the vehicle as a whole.
