Effects of nozzle and air vent size on sediment sampler performance / P. Engel and I.G. Droppo. : En13-5/92-06E-PDF
"Using dimensional analysis and experimental datas, it has been shown that the performance of the US DH-81 sampler is highly dependent on the relative size of nozzle and air vent diameters. It is shown that the sampler has a distinct flow control regime which depends primarily on the relative size of the nozzle intake diameter and the air vent diameter. If flow control is at the nozzle, the flow rate into the sampler can be significantly increased by changing certain geometric properties of the nozzles. If flow control is at the air vent, iso-kinetic performance can be achieved by varying the air vent diameter. It is further shown that the Sampler Performance Coefficient is strongly dependent on a dimensionless variable designated as the Sampler Number which accounts for the viscosity of the water when the sampler operates under nozzle control and viscosity of the air in the sampler when flow control is at the air vent"--Abstract.
