ASME - JSME - KSME Joint Fluids Engineering Conference AJKFluids 2019

Jul 28 2019 - Aug 01 2019 Hyatt Regency San Francisco, 5 Embarcadero Center, San Francisco, CA 94111 https://event.asme.org/AJKFluids

AJKFluids is the ASME - JSME - KSME Joint Fluids Engineering Conference, an international fluids engineering conference held every 4 years. This year's event is in San Francisco from July 28 to August 1, 2019.

TSI is a Bronze Sponsor for this event and TSI's Dr. Stamatios Pothos is Chair for ASME's Fluid Measurement & Instrumentation Technical Committee. In addition to exhibiting, TSI experts will present six papers at #AJKFluids. Please join us for these presentations by our fluid mechanics team.

Title, Date & Time TSI Author(s) Abstract Excerpt
Measurements of Velocity and Size in Two-Phase Flows using Volumetric PIV | Monday, July 29, 13:30
  • Dr. Ruben Hortensius
  • Dr. Daniel Troolin
  • Dr. Aaron Boomsma
  • Dr. Stamatios Pothos
A study was conducted using a volumetric particle image velocimetry (PIV) system to investigate the flow of a falling liquid raindrop and the continuous gaseous phase around it. Of particular interest was the desire to capture the velocity and size of the raindrop, as well as the velocity of the surrounding flow field, simultaneously and without the use of a secondary illumination source.
Development of a Flexible, Four-Camera Volumetric PIV System for Tow Tank Applications | Monday, July 29, 15:45
  • Dr. Ruben Hortensius
  • Dr. Stamatios Pothos
  • Mr. Mark Cecconi
Traditionally, PIV experimentation for hydrodynamic, marine, and biological applications have been carried out in water tunnel facilities where the instrumentation is safely located outside of the facility. Due to practical constraints, this has often resulted in limited ability to conduct experiments at large scale or high magnifications. To overcome this, submersible PIV systems have been developed, allowing for PIV experimentation in facilities such as towing tanks.
Droplet Sizing of Opaque Liquid with Integrated Transmitting and Receiving Optical Arrangement | Wednesday, July 31, 13:30
  • Dr. Wing Lai
  • Dr. Daniel Troolin
A number of industrial applications require the precise sizing of droplets. Some examples are spray drying in drug formation and ink jet printing for TV panels. The technique of ink jet printing for making TV panels requires the droplets emitting from the printer nozzles to be monodisperse and uniform for a long period of time. Phase Doppler system has been considered to be the best approach to measure the droplet size for this particular application.
DPIR: Dense Particle Identification and Reconstruction for Dual Frame and Time-Resolved Volumetric Particle Tracking Velocimetry (PTV) | Wednesday, July 31, 15:45
  • Dr. Aaron Boomsma
  • Dr. Daniel Troolin
  • Dr. Stamatios Pothos
Volumetric techniques are used extensively in the field of experimental fluid mechanics to provide researchers with the ability to measure three-component velocity fields in a volume. However, the accuracy of these methods strongly depends on the algorithms developed and used from aspects related to particle reconstruction and velocity reconstruction. Dense Particle Identification and Reconstruction (DPIR) is a novel technique that focuses on improving the accuracy and the reconstruction yield of both traditional dual-pulsed dual-frame as well as recent time-resolved Particle Tracking Velocity (PTV) data.
Considerations for Simultaneous Particle Image Velocimetry (PIV) and Laser Doppler Velocimetry (LDV) Measurements in Experimental Fluid Mechanics | Thursday, August 1, 10:00
  • Dr. Stamatios Pothos
  • Dr. Aaron Boomsma
  • Dr. Daniel Troolin
In the field of Experimental Fluid Dynamics, researchers have been using several techniques for the last 40 years. However, the two most important ones, and the ones that have been used with the highest frequency are: Laser Doppler Velocimetry (LDV) or Laser Doppler Anemometry (LDV) and Particle Image Velocimetry (PIV). In this presentation, we will be discussing several practical considerations for performing simultaneous PIV and LDV measurements.
PIV Leak Assessment of N95 Respirators | Thursday, August 1, 13:30
  • Dr. Daniel Troolin
  • Dr. Wing Lai

N95 filtering face piece respirators are helpful for protecting workers from breathing harmful particulates. However, if the mask is used in such a way that a leak develops, the worker may be at risk. This study uses particle image velocimetry (PIV) to assess the flow around an N95 respirator with a leak located at the bridge of the nose.
