AB  - With the knowledge that the air resistance acting on the body of automobile when it is driven at high
velocity is directly related to the fuel efficiency, it is now being considered as a highly important issue in
designing of automobile. This study aims to research how the velocity, pressure and phenomenon of
turbulence due to the air flow occurring around the shark antenna of automobile are generated when the vehicle
is running and what effects they have. In this study, commercially available shark antenna models are 3D
modeled with CATIVA design program and the simulated flow analysis was executed on these models by using
ANSYS finite-element analysis program. After having 3D designed the shark antenna models for each of the
configurations, it was possible to confirm the characteristics of the air flow of each of the shark antenna models
by executing flow analysis. As the results of the research, it was determined that the K-type shark antenna
model is the most appropriate model for application to vehicles since it displayed lower values in all the
comparison items including maximum flux, maximum pressure and distribution area of high pressure in
comparison to those of the H-type and G-type shark antenna model. Accordingly, it is deemed that this model
can make contributions towards the reduction in the resistance against air and the ensuring improvement of
fuel efficiency, etc. This study is on the research of the air flow of shark antenna applied to automobiles. It is
deemed that the data secured through the corresponding research can be used as basic data for more advanced
shark antenna design and researches related to the characteristics of air flow of automobile being driven.
