Review article

The article presents the methodology and results of the study of the influence of the distance from the obstacle to the cut of the outlet pipe of the fan case of the cooling system of the automobile engine on the nature of the air flow distribution in front of the radiator. The studies were carried out on a specially made laboratory installation that provides measurement of the air flow velocity at fixed points in front of the radiator. As a result of the research, there were obtained response surfaces that describe the distribution of the air flow in front of the radiator at different distances from the obstacle to the outlet of the fan case. On this basis, there was determined the optimal distance from the obstacle, which provides the most uniform radiator blowing.
