An improved immersed boundary method for turbulent flow simulation on Cartesian grids is
proposed. To determine the appropriate boundary conditions, near-wall approximation of …

The reduced dissipation approach is applied to AUSM-family flux functions of SLAU2 (as
well as its predecessor, SLAU) and AUSM+-up for high resolution simulations. In this …

We investigate the onset of three-dimensionality in a Mach 5 slender-double-wedge flow as
the turn angle at the compression corner increases. Beyond a critical angle, the two …

Plasma discharges in electromagnetic thrusters often operate with weakly-collisional,
magnetized electrons. Macroscopic models of electrons provide affordable simulation times …

Transonic turbulent flows around the NASA Common Research Model are simulated to
investigate the capability of the Cartesian-grid-based flow solver UTCart in three …

This paper describes a shape exploration and multidisciplinary optimization method of
unconventional semirigid nearing space airships. The approach includes several improved …

Based on the biaxial experiment data of the membrane material under hot and cold
