Well-posedness results for a class of complex flow problems in the high Weissenberg number limit
… of this boundary layer by transforming to Lagrangian coordinates. In contrast to the possible ill-posedness of Prandtl's system in Newtonian fluids, we prove that in non-Newtonian fluids the stress boundary layer problem is well-posed.

Numerical Methods for All Mach Number flows for Gas Dynamics
… last chapter deals with the piston problem in Lagrangian coordinates treated by a semi-implicit scheme. The implicit treatment of the boundary conditions is originally developed in the thesis. It is shown that for very low Mach number the scheme is able to recover the adiabatic solution with …

Multiscale continuum thermodynamics based modeling of transport mechanisms and starch expansion during extrusion
… were transformed from the moving Eulerian coordinates to the stationary Lagrangian coordinates. Good agreements between the simulated and the experimental values of surface temperature, moisture content and expansion ratio of the extrudates at different extrusion conditions were obtained. …
