    Purpose. To assess unenhanced magnetic resonance imaging (MRI) in the preoperative evaluation of obstructive epiphora in patients undergoing dacryocystorhinostomy (DCR) and in particular, to evaluate the efficacy of this technique in the detection of the exact level of obstruction occurring in the naso-lachrymal duct (NLD).

APPARATUS Multinozzle-Duct Pilot Model The test apparatus was a 1/3-scale model of a proposed full-scale tunnel. It consisted of three nozzles, used to expand the flow, followed by a constant- area duct. The basic geometry and dimensions of the model apparatus are shown in figure 1.

The interior nozzle is cm ( in.) long and the exterior Experimental evaluation of a pilot multinozzle-duct apparatus. Washington: National Aeronautics and Space Administration, Scientific and Technical Information Office ; Springfield, Va.: For sale by the National Technical Information Service, Experimental evaluation of a pilot multinozzle-duct apparatus.

A pilot multinozzle and duct were tested at ambient enthalpy to evaluate the suitability of such apparatus for testing thermal protection system panels mounted in the sidewalls of the duct downstream of the nozzle array.
