An inflow turbulence generation method for large eddy simulation and its application on a standard high-rise building

Baifeng Ji et al.

Summary: A method named reusable wind tunnel replication method (RWTR) for generating inflow turbulence in large eddy simulation (LES) is presented and validated through numerical simulation of a real wind tunnel. The method is then applied to study wind effects on a standard high-rise building, with discussions on its advantages and limitations compared to wind tunnel measurements and previous numerical simulations. Several suggestions are provided for improving the method's performance, which is helpful in evaluating wind effects on buildings using LES.

A fractional PDE model for turbulent velocity fields near solid walls

Brendan Keith et al.

Summary: This paper introduces a class of turbulence models based on fractional partial differential equations with stochastic loads, where solutions are incompressible velocity fields with Gaussian distributions. Interaction between turbulence and solid walls is achieved through various boundary conditions, allowing flexibility in simulating near-wall statistics. Two simple physical applications are emphasized, including the reproduction of fully developed shear-free and uniform shear boundary layer turbulence, with the former validated using experimental data. Additionally, the paper discusses the generation of inhomogeneous synthetic turbulence inlet boundary conditions, inspired by contemporary numerical wind tunnel simulations, as well as calibration of model parameters and efficient numerical methods.
