Jet-breaker dimension effects on drop manhole performance

What is it about?

We optimized geometrical dimensions (length, width, sagitta, and angle ) of the plain jet-breaker which was suggested by Granata et al. (2014) for drop manhole as well as inlet pipe filling ratio. Manhole Laboratory model was studied and experiments were designed according to full factorial design. Then the obtained results were statistically analyzed and proper dimensions of the jet-breaker and optimum value of the inlet pipe filling ratio were suggested.

Why is it important?

I believe that this work is one of the pioneers' works which bring the powerful DoE methodology into the hydraulic and hydraulic structures filed of study. This advantageous methodology results in time- and cost-effective experimentation and causes unbiased and straightforward conclusion. Moreover, matrix dimensional analysis and its results could be used in similar studies.
