Combining direct and indirect sparse data for learning generalizable turbulence models
Xin-Lei Zhang, Heng Xiao, Xiaodong Luo +1
Learning turbulence models from observation data is of significant interest in discovering a unified model for a broad range of practical flow applications. Either the direct obser…
Comparison of Graphene Formation on C-face and Si-face SiC {0001} Surfaces
Luxmi, N. Srivastava, Guowei He +1
The morphology of graphene formed on the (000-1) surface (the C-face) and the (0001) surface (the Si-face) of SiC, by annealing in ultra-high vacuum or in an argon environment, is…
Re4: Scientific Computing Agent with Rewriting, Resolution, Review and Revision
Ao Cheng, Lei Zhang, Guowei He
Large language models (LLMs) serve as an active and promising field of generative artificial intelligence and have demonstrated abilities to perform complex tasks in multiple domai…
Onset of vortex shedding in flow past Rankine ovals
Zhaoyue Xu, Yi Liu, Hua-dong Yao +2
The Rankine oval is a classical geometry in potential flow, formed by superimposing a uniform stream with velocity U and a source-sink pair separated by distance 2a with strength m…
Statistics of Dissipation and Enstrophy Induced by a Set of Burgers Vortices
Guowei He, Shiyi Chen, Robert. H. Kraichnan +2
Dissipation and enstropy statistics are calculated for an ensemble of modified Burgers vortices in equilibrium under uniform straining. Different best-fit, finite-range scaling exp…
K2-V2: A 360-Open, Reasoning-Enhanced LLM
K2 Team, Zhengzhong Liu, Liping Tang +36
We introduce K2-V2, a 360-open LLM built from scratch as a superior base for reasoning adaptation, in addition to functions such as conversation and knowledge retrieval from genera…
