Reducing the Effect of Frost on Fruit Trees Using Axial Fans

Abstract

This research includes many important points, as it begins by clarifying the phenomenon of frost and its harmful effects and the resulting material and economic losses that are negatively reflected on the national economy. The reason for choosing the axial fan to do this task is the need for a fan with a high intensity and high efficiency, regardless of the pressure generated by this fan, and the inclined fan was chosen to passively the horizontal fans in the fight against frost. The mechanism of the system’s work was explained depending on the recorded temperatures and the critical temperature of the flowers, with the inclusion of an applied example for choosing the appropriate fan, and the effect of the angle of inclination of the fan and the height of the tower on the distance and area covered by the fan and on the abundance and ability of the fan.
