Using nodal analysis model

a treatment for evaluating the local losses by merging them into relevant pipes was proposed and equations for computing total losses were deduced. Consequently

a method considering both friction and local losses was developed for stable fuel piping system. Then

it was applied to a practical simplified aeroengine fuel piping system. A software based on this algorithm was developed with VBNET language. Besides

threedimensional numerical simulations were conducted for the fuel piping system as well. Results showed that local loss affected the flow distribution a lot and directly determined the results. When solutions of the present method and numerical simulation were compared

they presented well agreement with each other with an error of ±10%.
