Abstract

Evaluation of drag force often requires wind tunnel experiments and can be prohibitively expensive if not impossible for large objects or systems. Computational Fluid Dynamics (CFD) aerodynamic analysis offers an alternative approach and can be used as a very effective tool in many industries: automotive, aerospace, marine, etc. The main objective of this research was design and analyze the effect of various speeds and angles of the air flow behaviour on the bicycle helmet in order to compare the results of drag force among three bicycle helmets using SolidWork Flow Simulation through CFD analysis. This research presents aerodynamic data for the three bicycle helmet model. The helmets were tested at a three different degree, from 0 degree to 30 degree, in increments of 15 degree. The helmets were tested at three speeds at each angle in order to best mimic actual riding conditions. A control road helmet was used to serve as a comparative tool. The testing results showed that Helmet 1 is the best helmet at all angles that offer drag reduction more than Helmet 2 and Helmet 3.
