FIELD: measurement technology, gears profiling field of flow velocities of steam of liquid. SUBSTANCE: invention is meant for decrease of nonuniformity of flow rate in exit section of device. Areas of flow sections of radial clearances across outlet and inlet are equal and opening angles of diffusers 1, 2 and 3 are chosen from relation specified in description of invention. Working medium flows over pipe-line 1 made in the capacity of external diffuser and gets between diffusers 1, 2 and 3 with certain geometry of sections which leads to uniformity of flows rate in exit section. Device can also used as inlet chamber of heat exchanger to distribute heat transfer agent over pipes. EFFECT: decreased nonuniformity of flow rate in exit section of device. 1 cl, 2 dwg |
