Resumo

Two methods used for simulating flow problems in engineering are Method of Characteristics (MOC)
and Smoothed Particle Hydrodynamics (SPH). This paper compares the results obtained using these two methods
for hydraulic transient in forced conduits. Both steady and unsteady friction losses are considered using the
unsteady model proposed by Vardy et al. [1]. The study findings obtained by in-house codes are compared with
the experimental results of Martins et al.
