A weakly compressible SPH method for RANS simulation of wall-bounded turbulent flows

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Zhongguo Sun, Xiangyu Hu, , | Summary: This paper presents a Weakly Compressible Smoothed Particle Hydrodynamics (WCSPH) method for solving the two-equation Reynolds-Averaged Navier-Stokes (RANS) model. The turbulent wall-bounded flow with or without mild flow separation, a crucial flow pattern in engineering applications, yet rarely […]

Quantum oscillations in a dipolar excitonic insulator

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Bo Zou, Kenji Watanabe, Takashi Taniguchi | Summary: Quantum oscillations in magnetization or resistivity are a defining feature of metals subject to an external magnetic field. The phenomenon is generally not expected in insulators without a Fermi surface. The observations of quantum […]
