Abstract Effect of convection on the distortion spatial self-phase modulation(SSPM)pattern in graphene dispersions has been investigated. When a Gaussian laser beam is transmitted through grapheme dispersions, interference pattern far-field first forms series circular rings, but upper half rings collapses rapidly after period time, forming stable distorted pattern. Experimental results show tha...

Heterogeneous chemical looping combustion (CLC) reactions and conjugate transports in large oxygen carrier particles were numerically investigated with computational fluid dynamics (CFD) approaches, which a simplified noncatalytic reaction model was implemented for reducing intraparticle modelling computation. Volumic gas-solid treated as surface based on the equivalent internal particle model....

The comes ab...

Deep and shallow convection calculations occupy significant times in atmosphere models. These calculations also present significant load imbalances due to varying cloud covers over different regions of the grid. In this work, we accelerate these calculations on Intel R © Xeon PhiTM Coprocessor Systems. By employing dynamic scheduling in OpenMP, we demonstrate large reductions in load imbalance ...

Cloud Vertical Structure (CVS) plays a crucial role in determining atmospheric circulation and the hydrological cycle. We analyzed CVS Stratiform Clouds with Embedded Convection (SCEC) occurring mei-yu front over central-eastern China based on conjunction of S-band Doppler weather radar, C-band Frequency Modulation Continuous Wave (C-FMCW) rad ar, Microrain Radar (MRR). Our results showed that ...

Being a critical factor affecting the motion accuracy of precision machine tools, structural thermal elongation ball screw unit is generally caused by comprehensive influence from heat generations screw-nut pair/bearings and time-varying ambient temperature. To resist 2 disturbances above to guarantee precisely original length shaft, an active coolant control strategy proposed in this paper. Th...

The Pacific–North American (PNA) teleconnection is a major mode of Northern Hemisphere wintertime climate variability, with well-known impacts on North American temperature and precipitation. To assess whether the PNA teleconnection has extended predictability, comprehensive data analysis is conducted to elucidate PNA evolution, with an emphasis on patterns of PNA development and decay. These p...
