Conditional Sampling of Turbulence Intensities and Reynolds Stress in Premixed Turbulent Flames
Combustion Science and Technology, 1984 Abstract Abstrac–-A two-color LDA technique has been developed for conditional sampling of turbulence intensity and Reynolds stress in premixed turbulent flame. To sample conditionally in the unburned reactants, silicone oil aerosol which burned and evaporated by combustion is used to seed the flow.

Atmospheric Turbulence Phase Reconstruction via Deep Learning Wavefront Sensing
SensorsThe fast and accurate reconstruction of the turbulence phase is crucial for compensating atmospheric disturbances in free-space coherent optical communication. Traditional methods suffer from slow convergence and inadequate phase reconstruction accuracy.

On the study of the FSO link performance under controlled turbulence and fog atmospheric conditions
, 2011 In this paper, the effect of turbulence and fog on the free space optical (FSO) communication systems for on off keying (OOK), pulse amplitude modulation (PAM) and subcarrier intensity modulation (SIM) based on binary phase shift keying (BPSK) is ...

Tomography Diagnostics of Turbulent Premixed Flame with Fine and Intense Turbulence
Journal of the Visualization Society of Japan, 1998 It is well-known that turbulent wake flow behind the grating which consists of fine cylindrical rods has many eddies with a uniform scale particular to the rod diameter, and exhibits a dominant peak in the frequency spectrum of the velocity fluctuation.

Evaluation of Eddy Viscosity Models in Predicting Free- Stream Turbulence Penetration
Journal of Applied Fluid Mechanics, 2013 Turbulence schemes have long been developed and examined for their accuracy and stability in a variety of environments. While many industrial flows are highly turbulent, models have rarely been tested to explore whether their accuracy withstands such ...

Study on hydraulic characteristics of step-pool system
Shui kexue jinzhan, 2014 Step-pool system is a typical bed micro-morphology in high gradient (>3%) mountain rivers,which creates extremely high turbulence intensity and thus dissipates most of the flow energy. An artificial step-pool system was constructed in the Wenxia River

Experimental Investigation of the Effects of Turbulence and Mixing on Autoignition Chemistry [PDF]
, 2010 The autoignition of acetylene, released from a finite-sized circular nozzle into a turbulent coflow of hot air confined in a pipe, has been the subject of a recent experimental study to supplement previous work for hydrogen and n-heptane.
