high-speed imaging

 Several digital high speed video motion analysis systems provide detailed visualizations of spray dynamics at speeds of up to 8000 frames per second.  Images acquired using the short pulse width of the 120 mJ dual-cavity Nd/YAG laser allow for the capture of  high-speed phenomena at frame rates up to 13 Hz.

particle imaging velocimetry

 Our TSI planar Particle Imaging Velocimeter ["PIV"] is a powerful tool for investigating the dynamics of the spray plume and near-field recirculation zones.
Extensions to the TSI PIV instrument include Planar Laser-Induced Flourescence ["PLIF"], Global Sizing and Velocity ["GSV"] and shadowsizing particle imagery ["SSA"]. 

spray chamber

 The primary 3.6m x 1.8m [12' x 6'] spray chamber allows
the safe and responsible testing of simulants, non-water fluids and slurries.
The chamber can be fitted with a variety of
1-, 2- and 3-axis traverses for automated spray sampling anywhere within the spray envelope.  

steam

 The lab is equipped and fully instrumented to operate dual-fluid atomizers with either compressed air or steam. Our in-house boiler can supply saturated steam at up to 90 kg/hr at 8.5 barg [200 pph at 125 psig]. The lab is instrumented to accommodate up to 450 kg/hr [1200 pph] with steam provided by a portable boiler 

pressure chamber

 A custom-built pressure spray chamber allows investigation of sprays behavior at environmental pressures of up to 37.9 barg
[550 psig].
Two Ø200mm quartz view ports allow optical access for PDPA and PIV measurements.

on-site

 spray research incorporated can provide on-site testing services for situations where laboratory studies do not suffice. For example, we have developed a custom insertion PDPA probe for full-scale mist eliminator carry-over evaluations at power plants. This probe eliminates the need for internal tracks and mounts.

wind tunnel

 A modular open-circuit wind tunnel features a unique configurable stilling/contraction section that supports either a 0.6m x 0.6m [24"x24"] or 0.9m x 0.6m [36"x24"] test section.
The axial vane fan delivers air flow velocities from 3 m/sec [10 fps] to a maximum of 25 m/sec [83 fps] 

spray dryer optimization

 Ranging in evaporative capacity from the lab-scale Buchi 190 and Yamato Pulvis GA-31, through the pilot-scale Yamato DL-41, and to the pre-production-scale Niro Mobile Minor, spray research incorporated  provides comprehensive spray dryer scale-up, optimization and troubleshooting services. 

fluids characterization

 Tests with non-water fluids, as well as extrapolations from water-based data, require accurate characterization of the physical properties of the fluids.
Utilizing its full suite of instrumentation, spray research provides viscosity, density, Surface Tension and refractive index characterizations over a wide range of temperatures and environmental pressures

custom experimental solutions

 With its fully-equipped prototype and fabrication shop, spray research incorporated can provide custom experimental setups.
