Unified Gas-kinetic Wave-Particle methods I: Continuum and Rarefied Gas Flow [PDF]
arXiv, 2018 The unified gas-kinetic scheme (UGKS) provides a framework for simulating multiscale transport with the updates of both gas distribution function and macroscopic flow variables on the cell size and time step scales. The multiscale dynamics in UGKS is achieved through the coupled particle transport and collision in the particle evolution process within ...

Role of phase distortion in nonlinear saturation of the unstable acoustic modes in hypersonic parallel flow boundary layer [PDF]
arXivWe analyze the role of the relative phasing in the nonlinear saturation of the unstable Mack modes in a hypersonic parallel flow boundary layer in two dimensions (2D). As the linearly unstable Mack modes extract energy from the mean flow, the perturbation energy cascades into higher harmonics as well as the mean flow. The higher harmonics are generated

Hypersonic turbulent wall boundary layer computations [PDF]
The Baldwin-Lomax algebraic turbulence model was modified for hypersonic flow conditions. Two coefficients in the outer layer eddy viscosity model were determined as functions of Mach number and temperature ratio.
