Рассмотрена многоступенчатая технологическая рециркуляция аспирационного воздуха в перегрузочные желоба ― возврат аспирируемого от укрытий технологического оборудования воздуха обратно в технологический процесс с целью снижения энергетических затрат за счет создания аэродинамического сопротивления на пути движения эжекционного воздуха и поддержания требуемых теплофизических параметров в оборудовании. Рекомендуется оснащать желоба одноступенчатыми рециркуляционными затворами с минимально возможным углом подачи воздуха навстречу потоку, эжектируемому перегружаемым сыпучим материалом, что повысит энергетическую эффективность систем вентиляции и сократит выбросы в атмосферу вредных веществ.

For better study of the airflow movement in the untwisting chamber of a pneumatic splicer, this paper uses a commercial computational fluid dynamics software FLUENT to realize the three dimensional numerical simulation for the characteristic of the airflows in the untwisting chamber. A three-dimensional grid and the realizable k- ε tur¬bulence model are used in this simulation. The characteristics of the air flows in different parts of the chamber are analysed according to the computed result. The airflow in the untwisting chamber can be divided into three regions in longitudinal section and two regions in cross section.

In this paper, the numerical simulation analysis of jlu fsae racing car aerodynamic character based on star-ccm+ was introduced. Several simulated situations had been set and the results of the situations were compared. The effect of the wheel rotating situation of the racing car out flow and aerodynamic character was concluded. It was found that the air flows surrounding the wheels and the wings of the racing influenced each other. When the rotating wheel situation was set during the simulation, the effect that the air flows influenced could be simulated more clearly and the result could be more calculatedly. It was necessary to set the wheel rotate when to simulate the racing car aerodynamic character. From the simulated results, it also could be seen that it was also necessary to take care of the wheel rotate when to do the racing car wind tunnel test.
