Facilities
UHP-RCM & HRR-Tof-ms platform
The first-of-its-kind platform couples a customized Ultra-High-Pressure Rapid Compression Machine (video and bottom left figure) and a High-Repetition-Rate Time-of-Flight Mass Spectrometry (top left figure), enabling characterization of fuel pyrolysis, oxidation and autoignion at 600–1400 K, 1–1000 bar, various equivalence ratios and diluent ratios, which is ideal to study atmospheric to supercritical chemistry.
In addition, heat release rate can be robustly extracted from recorded pressure-time histories.
This platform can be used to study the combustion characteristics of gaseous, liquid and solid fuels at conditions representative of heavy-duty, gas turbine and rocket engines.
The Flat flame burner
platform
The platform integrates a McKenna Burner, a gas-feeding system, a gaseous and particle sampling system, a thermal imaging system and a water-cooling system.
The downstream analyzers can accurately determine the emissions from the flame, including NOx, UHC, CO, CO2 and soot.
The platform can be used to detect the off-gas limits of SOFC systems, the carbon damping effect at anodes, laminar flame speed measurement, flame emission measurements. In addition, an infrared camera is used to capture the thermal field of the flame.
The "Holthuis and Associates Flat Flame Burner", referred to as McKenna Burner, is ideal for quality combustion analysis.
Flow Reactor
& Micro-GC Platform
The platform combines a fused silica flow reactor, a gas-feeding system, a gas sampling system, and a Micro-GC.
The flow reactor is able to generate a fully premixed homogeneous mixture with well-controlled temperature. The gas-feedings system can supply different gaseous into the reactor inlet at various flow rates. The Micro-GC can detect and analyze the concentration of different species from the extracted samples.
With this platform, pyrolysis and oxidation of gaseous and liquid fuels can be characterized at various temperatures and residence times.
Real-time
high-speed imaging Platform
The high-speed imaging platform combines two high-speed cameras, a Photron SA-Z high-speed camera mounted with a Questar QM-100 lens and a Chronos 2.1 high-speed camera from Kron Technologies equipped with a TCLO lens.
With the platform, droplet impact dynamics including coalescence, bouncing, partial coalescence, reflexive separation, etc., can be recorded at up to 40000 fps with a spatial resolution of 1024×512.
High-pressure laser-induced flame & soot imaging platform
The High-Pressure Flame/Soot Imaging platform couples a customized High-Pressure Burner Chamber, two counter-positioned McKenna Burners, a Laser System, and an Imaging System.
The laser system includes a PRO-290-10 Primary Nd: YAG Laser, a INDI-40-10-HG Secondary Nd: YAG Laser, and a PSCAN-LG-24-EG Tunable DYE Laser. The imaging system includes a “Princeton Instruments” PM4-1024I-SB-FG-18-P46 Intensified CCD Camera and an “Andor” iStar DH334T Intensified CCD Camera.
The platform enables PLIF and LII detection, which can be used to characterize the flame dynamics and soot/PAH characteristics at 1–100 bar.
super-computing platform
The platform includes a PILOT Supercomputing Platform (10 nodes, 4 TB memory) and a BUDA Supercomputing Platform (60 nodes, 12 TB memory), with over 3000 CPU cores and 20 GPU cards.
With the platform, high-accuracy quantum chemistry calculations, molecular dynamics calculations, quantum mechanics calculations can be efficiently conducted.
