Physical Review E 2011年 第2期83卷 026707-026707页
作者: Yu Chen Qinjun Kang Qingdong Cai Dongxiao Zhang The State Key Laboratory for Turbulence and Complex Systems (LTCS) Center for Applied Physics and Technology (CAPT) and Department of Mechanics and Aerospace Engineering Peking University Beijing People’s Republic of China Sonny Astani Department of Civil and Environmental Engineering University of Southern California Los Angeles California 90089 USA Earth and Environmental Sciences Division Los Alamos National Laboratory Los Alamos New Mexico 87545 USA Department of Energy and Resources Engineering Peking University Beijing People’s Republic of China
A lattice Boltzmann method on nonuniform quadtree grids is proposed. Our method employs the interpolation-supplemented lattice Boltzmann model. The advantages of the quadtree grid are preserved by using linear interpo... 详细信息

International Instrumentation and Measurement Technology Conference (I2MTC)
作者: Ferrero, Alessandro Salicone, Simona Politecn Milan Dipartimento Elettrotecn I-20133 Milan Italy
The evaluation of the spectral components of a signal by means of a DFT or FFT algorithm is subject to leakage errors whenever the sampling frequency is not coherent with the signal frequency. Smoothing windows are us... 详细信息
