Performance of the cut‐cell method of representing orography in idealized simulations [PDF]

open access: yesAtmospheric Science Letters, 2013
AbstractSeveral tests of a model with a cut‐cell representation of orography are presented: a resting atmosphere test, advection across a hill and a warm rising bubble over hills with different gradients. The tests are compared with results from terrain‐following models.

Study on accuracy of casting flow simulation [PDF]

open access: yesChina Foundry, 2017
In the field of casting flow simulation, the application of body-fitted coordinate (BFC) has not been widely used due to the difficulty and low efficiency of grid generation, despite the availability of good quality analysis results.

A Novel h–φ Approach for Solving Eddy–Current Problems in Multiply Connected Regions

open access: yesIEEE Access, 2020
A novel h-φ approach for solving 3-D time-harmonic eddy current problems is presented. It makes it possible to limit the number of degrees of freedom required for the discretization such as the T-Ω method, while overcoming topological ...

A generalised eigenvalue reweighting covariance matrix estimation algorithm for airborne STAP radar in complex environment

open access: yesIET Radar, Sonar & Navigation, 2021
To improve the space‐time adaptive processing (STAP) performance of airborne radar in complex environment, a generalised eigenvalue reweighting covariance matrix estimation algorithm called GERCM is proposed here. First, the interference plus noise (IPN)
