Stable and Efficient One-Way Modelling of Convective Disturbances in Laminar Boundary Layers: OWNS-Summation
Elliot J. Badcock, Shahid Mughal
One-way spatial marching methods separate upstream- from downstream-propagating disturbances using a rational approximation of a spectral projector. Among existing one-way Navier--…

A carrier-wave factored one-way Navier--Stokes method for boundary-layer instability modelling
E. J. Badcock, S. Mughal
We present M-OWNS, a spatial marching method that combines the carrier-wave factoring of the parabolised stability equations (PSE) with a recursive one-way Navier--Stokes (OWNS-R)…
