β¦ Synopsis
The formulation of a numerical solution method for the Navier-Stokes equations in domains with cylindrical boundaries based on a hybrid spectral -finite difference approach is presented. The main contributions of the present paper are complete proofs for the pole conditions for scalar and vector fields and the modified pdes for the streamfunction modes that are shown to possess solutions satisfying the pole conditions.

Short fatigue crack propagation often determines the service life of cyclically loaded components and is highly influenced by microstructural features such as grain boundaries. A two-dimensional model to simulate the growth of these stage I-cracks is presented. Cracks are discretised by displacement
In a recent study we showed that the two-fluid (TF) formulation can be used in the direct numerical simulation (DNS) of bubble-(or particle-) laden decaying isotropic turbulence with considerable saving in CPU-time and memory as compared to the trajectory approach employed by many researchers. In th
