This study utilizes a hybrid aeroacoustic model to investigate how airfoils with spanwise wavy geometries can be used to reduce trailing-edge noise alongside improving the …
A digital twin (DT) is a numerical model (in silico) of a system that runs alongside its physical counterpart and exchanges (bidirectional) information with it. The digital twin, once suitably …

A recently developed hybrid absorbing boundary condition (ABC) can significantly suppress artificial boundary reflections by inserting a transition area between the boundary and the …
In this study, a versatile and general three-dimensional hybrid aeroacoustic model is presented for low Mach number turbulent flows. A dual-domain approach is adopted, with …
The FWI is formulated as a nonlinear optimization problem that traditionally uses local (derivative-based) minimization to find the scalar field of properties that best represents the …

The finite-difference (FD) scheme is popular in the field of seismic exploration for numerical simulation of wave propagation; however, its accuracy and computational efficiency are …
A hoped-for outcome from high-order CFD methods, in addition to achieving accurate solutions on fine grids, is to achieve useful answers on coarse grids. In this paper we note …
