Characteristics of Gas-Solid Reaction on Particle Surface in Isotropic Turbulence Field

Determination of Statistical Characteristics of Isotropic Turbulence

Ultrasonic flow measurement technology has the potential to significantly improve flow measurement accuracy beyond that presently achieved. However, current applications fail to achieve theoretical accuracies because of turbulence effects on ultrasonic wave transit time. Herein, the ultrasonic flowmeter equation is reconsidered, where the effects of turbulent velocity and sound speed fluctuatio...

Coagulation-induced particle-concentration fluctuations in homogeneous, isotropic turbulence

The turbulent coagulation of micron-sized colloidal particles in a liquid is controlled by the shearing motion produced by Kolmogorov scale eddies. The rate of energy dissipation has fluctuations which vary over the integral length and time scale in a homogeneous, isotropic turbulent flow. We present a model of the particle concentrations and coagulation rates in a set of fluid packets that are...

Effect of inter - particle collision in particle - laden homogeneous isotropic turbulence

Submitted for the DFD10 Meeting of The American Physical Society Effect of inter-particle collision in particle-laden homogeneous isotropic turbulence OHJOON KWON, CHANGHOON LEE, Yonsei University — It has been known that Inter-particle collision of small spherical particles in particle laden homogeneous isotropic turbulence modifies the statistical characteristics of particle behaviour. For ex...
