Understanding the dynamics of riser design in skyscrapers

How gravity, volume and thermodynamics play a role in smart riser design. This article will introduce some basics of pipe risers design and performance, explain some considerations in using different expansion joints in pipe risers, and briefly describe some of the codes and standards regarding guiding and supporting risers

Suction Diffuser Flex and Pump Applications

When poorly developed flow enters the pump impeller, it strikes the vanes and is unable to follow the impeller passage. The liquid then separates from the vanes causing mechanical problems due to cavitation and vibration, and performance problems due to turbulence and poor filling of the impeller…

Suction Diffuser Flex Operating Principles

When the Suction Diffuser Flex Rotation-Vane is placed immediately upstream of an elbow, it rotates the flow entering the elbow. As a consequence, the fluid negotiates the turn with all the streamlines traveling approximately the same distance (equal flow path lengths) from entrance to exit, as illustrated in Figure 1(a)-right, and…

Metraflex Suction Diffuser Flex in a Reducing Elbow Simulation

The Metraflex six-bladed Suction Diffuser Flex flow conditioner was analyzed to determine its effect in a 4″ to 3″ reducing elbow with a water velocity of 5 feet per second. The simulation was conducted using CFdesign version 9.0 from Blue Ridge Numerics, Inc.
