Experiment and Numerical Simulation of Resistance Coefficient of 90° Bend Pipe with Low Reynolds Number in HVAC

Tao Li

Abstract

The resistance coefficient of 90° bend pipe is studied and the pressure and speed distribution in pipe are analyzed by using the experiment and numerical simulation method.The resistance loss mechanism and change rule of single local component is found out by discussing the change rule and mechanism of resistance loss and measuring the effect length caused by local component.
