CFD modeling for the estimation of pressure loss coefficients of pipe fittings: An undergraduate project

This work reports the outcomes of a senior undergraduate project done as part of a CFD course offered at Curtin University, Malaysia. Pressure loss coefficients for single phase flow through 90 degree bend has been estimated using CFD simulation. It is evident from the results that a validated CFD model is a reliable and cheap tool for loss coefficient estimation of any combination of pipe fitting and complex fluid / flow. © 2015 Wiley Periodicals, Inc.
