Aerodynamic flow analysis on skateboard using computational fluid dynamics

This study aims to analyze the shape of the speed line, flow trajectory, resistance, and coefficient of resistance received by the skateboard. The aerodynamic flow testing method on a skateboard is carried out using the flow simulation available on Solidworks. The model of the skateboard made there are 2 variations. Model 1 on the front and back form the same angle of 30o and model 2 on the front flat and back forms an angle of 30o. The results of the study showed that the shape of the skateboard model 2 has a smoother flow pattern on the top of the board than the type of skateboard shape model 1 which produces a backflow rotation on the top of the board. And supported by the results of the comparison of model 1 and model 2, the highest value is taken in each model with a speed of 35 m/s with a density of 1.225 kg/m^3 then the resistance value in model 1 is 10.94169313 N and the coefficient of resistance is 10.94169313 N. the resistance is 9.06215e -07 and while in model 2 the resistance value is 6.642596152 N and the coefficient of inhibition is 7.11141e-07.
