The purpose of this study was to compare three common types of car seat in Iran on the driver's fatigue and muscle discomfort. Methods: Ten participants completed 2 hours of simulated driving for each of the three type of car seat in different days ...
In this study, a numerical computational fluid dynamics study is conducted in order to predict the aerodynamic forces on the NP car. The turbulent air flow around the car is modeled using the realizable k-ε model. First, results are validated against those presented for the Ahmed’s body. Next, the fluid flow around the car is simulated for different car speeds ( to mph) and fl...
