A study of a supersonic capsule/rigid disk-gap-band parachute system using large-eddy simulation被引量:1
《Applied Mathematics and Mechanics(English Edition)》2021年第4期485-500,共16页Sheng GONG Chuijie WU 
Project supported by the National Natural Science Foundation of China(No.11372068);the National Basic Research Program of China(973 Program)(No.2014CB744104)。
The aerodynamic performances and flow features of the capsule/rigid disk-gap-band(DGB)parachute system from the Mach number 1.8 to 2.2 are studied.We use the adaptive mesh refinement(AMR),the hybrid tuned center-diffe...

A Theoretical Analysis of Torque and Superlubric Motion in Bilayer Graphene Disks
《Wuhan University Journal of Natural Sciences》2015年第2期173-179,共7页LI Jianwen LIU Nianhua 
Supported by the National Basic Research Program of China(973 Program)(2013CB934200);the Key Program of the National Natural Science Foundation of China(10832005);the National Natural Science Foundation of China(11264030)
To identify the relation between torque and superlubric motion, we investigate the interlayer sliding behavior of two graphene disks with numerical computation methods. The potential energy, lateral force and torque b...
