ZM8208 Energy Losses in Piping Elements Fluids Engineering Training Equipment Teaching Equipment Didactic Equipment1. Introduction to the equipment
1.1 Overview
In engineering, pipeline transport of fluid is an extremely important method. When the fluid flows in the pipeline, energy loss will occur. The energy loss of the fluid in the pipeline mainly includes two forms: along-the-line resistance loss and local resistance loss. Along-the-line resistance loss is mainly caused by the friction between the pipeline and the fluid, while local resistance loss is caused by the presence of various other pipe fittings in the pipeline, such as elbows, sudden expansion or contraction of the flow channel, valves, tees, etc. When the fluid flows through the local area of these pipelines, the flow velocity and direction are forced to change sharply, resulting in collision of fluid particles, vortices, secondary flows, flow separation and reattachment to the wall. Compared with along-the-line resistance loss, local resistance loss is much larger, so the focus will be on local resistance loss.
SSR20240307A05 Energy Loss in Pipeline Components (Add-on Module) is an experimental device for studying the local resistance loss of various pipeline components.
