Experimental investigation on discharge coefficient of jet impingement holes within semi-confined channel
An experimental investigation for determining the discharge coefficient of jet impingement holes within semi-enclosed channel was performed.According to the jet impingement configurations with single row or double row holes
the effects of the holes arrangement and flow parameter on the discharge coefficient were considered
such as: the span holes pitch-to-diameter ratio
the streamwise holes pitch-to-diameter ratio
the impingement distance-to-diameter ratio
the jet oblique angle and the jet Reynolds number.Comparatively
the above factors on the discharge coefficient were discussed.
