Cars on Flooded Streets
by Hasuwannakit, C., Millana, N.A., Yoadsanit, S.
Abstract
A model car was pushed and then allowed to freely decelerate through water with depths ranging from 0.0 to 4.0 cm. Water depths that submerged only the wheels, not reaching the body of the car, were tested. It was shown that the rate of increase of drag force decreases as depth of water increases, and the drag force is proportional to the velocity of the car. The drag force was almost constant for water depths above 75% of the wheel’s radius, for a given velocity.
