IN HYPERSONIC flow computations, it is a key issue to predict surface heating accurately.
However, it is still challenging to compute hypersonic flows, because there are always …

Accurate prediction of real gas flows with strongly variable properties is an essential
prerequisite for turbomachinery performance analysis. This paper presents a density-based …

In supersonic wind tunnels, the airflow at the exit of a convergent-divergent nozzle is
affected by the connection between the nozzle and test section, because the connection is a …

ABSTRACT A multi-fidelity optimization technique by an efficient global optimization process
using a hybrid surrogate model is investigated for solving real-world design problems. The …

This application paper presents a comprehensive experimental eval-uation of the suitability
of Topological Data Analysis (TDA) for the quantitative comparison of turbulent flows …

The flow speed around a helicopter has a wide variation from very low (M~ 0.1) to transonic
(M~ 0.9) when full configuration and full flight regime are considered. Special care must be …

We propose a novel Mach-uniform numerical model for 2D Euler equations on unstructured
grids by using multi-moment finite volume method. The model integrates two key …

In low speed flow computations, compressible finite-volume solvers are known to a) fail to
converge in acceptable time and b) reach unphysical solutions. These problems are known …

A variable-pitch-controlled quadrotor drone was simulated in the ground effect using a high-
fidelity CFD solver. In contrast to a single rotor in the ground effect, which has been …
