Study of flow aerodynamics in a channel with dumbbell-shaped dimples


The paper deals with the study of aerodynamic
resistance in a channel with dumbbell-shaped dimples on the surface and with smooth walls. It has been found that the hydraulic resistance of a channel with dumbbell-shaped dimples is higher than of a smooth one. The surface of the channel of the proposed design is also higher. It can be used for the intensification of heat transmission in recuperative heat exchangers of ventilation systems. The numerical study of the flow in a rectangular channel with one-sided arrangement of dimples of proposed geometry has been carried out. It has been determined that the use of such dimples at small flow rates near the inlet (1-0.5 m/s) will increase the rate of gas flow near the surface with dimples in comparison with a smooth wall to 20 %. When the flow rate near the inlet is 16.5 m/s, the areas with lower rates appear near the dimples.

Design of roads on approaches to a mountain pass

DUYUNOV Petr 41-48 p.

The paper dwells upon various designs of roads on approaches to a mountain pass with the use of «loops» and serpentines. When designing serpentines it has been offered to calculate the magnitude of the transition curve on the base curve taking into consideration the optimum safety speed, and on the reversed curve – the speed provided by the basic curve rather than its radius. This allows to adjust a road layout to the relief form at the most, causing minimum possible damage to the environment. It has been recommended to lay a road on the approaches to a mountain pass focusing not on the limiting for the given road category longitudinal gradient, but on the «ruling» one, which is smaller than the limiting by the value of its decreasing on curvatures of small radii. The value of decreasing the limiting longitudinal gradient for roads located in the mountain massif of Central Asia, taking into account the position of the ridge in the mountain massif and slope exposure has been determined. The use of «loops» and serpentines for development of roads on a mountain slope has been calculated. Their comparison has been made. In many respects, the loop turned out to be more preferable than serpentines.

Irregular architectural ensemble and group-form

IVANOVA Elena 63-67 p.

The main purpose of this article is making a definition of irregular ensemble’ compositional and morphological features, as a specific architectural and town-planning phenomenon. Irregular architectural ensembles, unlike regular ones, are capable of more flexible reaction on the dynamics of living conditions. An research on ensembles of this type can be useful for architectural design and urban planning. This study of the morphology of irregular architectural ensemble represents the phenomenon of “group form” – defined as low-ordered, incomplete association of volumes and spaces. “Group form” is opposed to the regular architectural ensemble as a compositional form. The phenomenon of irregular ensemble is treated as an intermediate between the two oppositions, and is defined in the article as compositional group form.
