Vector-valued multidimensional signal processing and analysis in the context of fluid flows
… field from random samples in the context of the Particle Tracking Velocimetry (PTV) or Particle Imaging Velocimetry (PIV) experiment. The theory of recovering vector-valued signals from random point processes is generalized from those for scalar-valued ones. Two interpolation methods are …

Evaluation of a Particle Sampling Probe to Measure Mass Concentration in Particle-Laden Flows
Particle ingestion is a prevalent issue for jet engines. During operation, sand and ash particles enter the engine and can cause serious problems, including erosion and buildup of Calcia-Magnesia-Alumina-Silicate (CMAS) deposits. Analyzing the particle mass concentration of the airflow can help …

An Experimental Study of Soot Formation in Dual Mode Laminar Wolfhard-Parker Flames
… with temperature using Thermocouple Particle Densitometry (TPD). Soot volume fraction, particle size and particle number density fields were measured using laser light scattering and extinction. Gas velocities were measured using Particle Imaging Velocimetry (PIV) on the non-premixed …

The flow structure of interacting barchan dunes
High-resolution particle-image velocimetry (PIV) experiments have been conducted over a fixed-bed to examine the effects of interacting barchan dunes on the flow structure. The barchan dune models were based upon an idealized contour map, the shape and dimensions of which were based upon previous …
