A comparison between physical and virtual experiments of convective heat transfer between head and bicycle helmet
(2017) AHFE 2017 International Conference on Human Factors in Simulation and Modeling, 2017 In Advances in Intelligent Systems and Computing 591. p.517-527- Abstract
Thermal performance of five bicycle helmets was evaluated with a thermal manikin head with six zones. Evaluation was made with physical and virtual experimental methods. Ambient temperature maintained at 24 °C and surface temperature of the thermal manikin head was set to 34 °C. Experiments were performed for air velocities of 1.6 m/s and 6 m/s. Heat transfer (W) of four thermal zones was recorded for five helmets and compared with a nude thermal manikin head to assess thermal performance. Virtual experiments were performed using commercial CFD codes with a realizable k-e turbulence model. Correlation coefficients of 0.78 (1.6 m/s) and 0.79 (6 m/s) were found between physical and virtual experiments. A combined physical and virtual... (More)

A combined physical and virtual evaluation methodology allows creating a design iteration process with virtual prototypes, physical prototypes and commercially available helmets.
