Approximating a branch of solutions to the Navier--Stokes equations by reduced-order modeling
Maxim A. Olshanskii, Leo G. Rebholz
This paper extends a low-rank tensor decomposition (LRTD) reduced order model (ROM) methodology to simulate viscous flows and in particular to predict a smooth branch of solutions…

Speed-direction description of turbulent flows
Maxim A. Olshanskii
In this note we introduce speed and direction variables to describe the motion of incompressible viscous flows. Fluid velocity is decomposed into , with…
