A new snow fence with airfoil snow plates to prevent snowdrift formation and improve visibility on roadways was developed. It was designed in accordance with aerodynamic principles, and its performance evaluated in a wind tunnel test in which natural snow particles were used to simulate blowing snow. Snowdrifts and visibility blockage behind the snow fence were found to be caused by the alternating rolling-up of the bottom gap flow and shear layer separatsion from the top of the fence. Use of airfoil snow plates prevented the alternating rolling-up of the bottom gap flow and shear layer separatsion from the top of the snow fence. On the basis of this finding, air foil snow plates of optimum configuration were designed to prevent the alternating rolling-up of the flow behind the snow fence. As compared to the conventional one, this newly developed snow fence with the airfoil snow plates performed well in preventing the formation of snowdrifts and in improving visibility.
