Резюме: В статье рассмотрены сравнительные преимущества и недостатки различных типов гасителей неравномерности полей скоростей. Численное исследование проводилось с помощью программного комплекса ANSYS FLUENT. Эффективность гасителей неравномерности полей скоростей определялась исходя из их способности обеспечить равномерное поле скоростей с наименьшим гидравлическим сопротивлением совместно с сильнейшими источниками возмущений, таких как шиберная задвижка и шаровой поворотный клапан. Разработан новый гаситель неравномерности поля скоростей, состоящий из двух перфорированных конических поверхностей, который обладает высокой эффективностью на малом расстоянии от его выходного сечения.

Abstract: The present paper presents a comparison of the performance of different flow conditioners. The numerical investigation is carried out using ANSYS FlUENT. Flow conditioners efficiency is evaluated on the basis of the ability of these devices to produce a uniform velocity profiles with low pressure loss under high-level disturbance conditions, such as those produced by gate and ball valves. A new flow conditioner device, which consists of two perforated conic plates has been designed, and demonstrated a high performance within a short distance downstream of the flow conditioner.
