DEVELOPMENT AND RESEARCH OF VIBRATION IRREGULARITY IN PIPING SYSTEMS AND PATHS OF TURBOMACHINES ON THE BASIS OF MATHEMATICAL MODELING

Abstract

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.
