“…Parameters considered in this work are show on table 1. The ground simulation for this paper is moving ground with rotating wheels as mentioned before, which is the condition close to the real operating condition, according to [1] and [8] and the turbulence model considers swirl flow due to water perturbations.…”

Within the advances in CFD codes and HPC cluster size and processing capacities, multiphase CFD simulations became more feasible not only on research projects but also in production level. This work presents a simulation analysis of an automotive vehicle crossing certain height of water and analyzing the water ingestion by the air intake system and also the pressure load due to the water level and splashes reaching the vehicle. All the calculations were performed by Computational Fluid Dynamics, considering the car crossing 300mm of water height at 20 kph with a simulation time enough to the water reaches the whole car length. Results show the water path at the snorkel region and some part pressure load examples which can be used as an input for structural simulations to evaluate this part at this particular condition.

“…For both steps, CFD simulations were performed considering a full regular production car with rotating wheels, CRFM drop pressures and full underhood representation. The vehicle is assembled in a virtual Wind Tunnel, with dimensions and parameters similar to GM Wind Tunnel [6], same proposal of [1] work. Parameters are exposed in Table 1: The ground simulation for this paper is moving ground with rotating wheels as mentioned before, which is the condition close to the real operating condition, according to [5] and [11].…”

This study refers to the Computational Fluid Dynamics, demonstrating a comparative between the drag coefficient and the frontal area of a current production car with the same values obtained from a conceptual proposal of removing the outside rearview mirrors of this same vehicle. Both cases were simulated in a virtual wind tunnel with moving ground and rotating wheels condition at speed of 100 kph, aiming to represent the best way a car moving on a highway. The main objective of this paper is improving the efficiency of automotive vehicles by replacing the current outside rearview mirror for cameras placed in smaller structures. The first simulation showed that by removing the outside rearview mirrors both the frontal area of the car and the drag coefficient, which has direct influence on fuel economy calculation, are smaller compared to current solution. As a complement for the study, two additional cases presenting alternatives on the camera positioning were simulated in similar condition of the study presented first and the drag coefficient, velocity path lines, pressure and wake were compared, demonstrating the performance of each case.

“…Assim como no trabalho de BUSCARIOLO e KARBON (2011) [2], os mesmos parâmetros são utilizados para a simulação computacional, e são expressos na tabela abaixo, O total de elementos volumétricos da malha, considerando um tamanho de malha superficial média de 10 mm, é de aproximadamente 60 milhões, levando em conta o túnel de vento. O tempo total de processamento é de aproximadamente 30 horas utilizando 288 CPUs.…”

“…O assoalho e a caixa de rodas são responsáveis pela maior parte da força de arrasto, aproximadamente 55%. BATCHELDER (2009) Alguns trabalhos foram desenvolvidos a fim de analisar a influência da abertura da roda no coeficiente de arrasto para veículos sedan de alta performance (Buscariolo e Karbon, 2011 [2]). O estudo foi realizado utilizando as ferramentas de CFD com o objetivo de análise do comportamento aerodinâmico das rodas.…”
