Theoretical investigations of snow particles movement in vertical feeder of rotary snow blower

Abstract

The paper considers the description of the movement of a snow particle in a vertical feeder of a rotary snow blower, taking into account the impact phenomenon. The main purpose of the presented studies is to determine the general patterns when a snow particle hits a fixed shell of a vertical feeder, as well as to substantiate the conditions for the end of the impact and the transition to describing the motion of a snow particle by equations that do not take into account impact effects. To achieve this goal, a one-factor numerical experiment was carried out, in which the variable parameter was the value of the velocity recovery coefficient upon impact. As a result, possible trajectories of the movement of a snow particle, the nature of the change in the speed of movement of a snow particle, due to emerging impacts on a fixed surface, are obtained, as well as a condition is proposed that can be used as a condition for the end of the impact and consideration of further impactless particle motion. A comparison is made between the shock pulse and the pulse of the normal reaction of a vertical wall. An algorithm for determining the motion of a snow particle in the presence of one non-retaining bond and taking into account its impact is proposed.
