    This book offers a compact primer on advanced numerical flux functions in computational fluid dynamics (CFD). It comprehensively introduces readers to methods used at the forefront of compressible flow simulation research. Further, it provides a comparative evaluation of the methods discussed, helping readers select the best numerical flux function for their specific needs.

    The first two chapters of the book reviews finite volume methods and numerical functions, before discussing issues commonly encountered in connection with each. The third and fourth chapter, respectively, address numerical flux functions for ideal gases and more complex fluid flow cases― multiphase flows, supercritical fluids and magnetohydrodynamics. In closing, the book highlights methods that provide high levels of accuracy.

    The concise content provides an overview of recent advances in CFD methods for shockwaves. Further, it presents the author’s insights into the advantages and disadvantages of each method, helping readers implement the numerical methods in their own research.

  • Improvement of the Aerodynamic Characteristics of Wings with 3D Laminar Separation Control using the Moving Surface Method

    OGAWA Suguru, KITAMURA Keiichi

    <p>In recent years, research is actively being conducted on unmanned air vehicles (UAVs), micro-air vehicles (MAVs), and Mars airplanes. In these flights, there is a common problem that laminar separation likely occurs due to the low Reynolds number (Re = 10<sup>4</sup>–10<sup>5</sup>) flight conditions. Laminar separation causes a reduction in the lift-to-drag ratio and hence needs to be controlled. In this study, we utilize the “moving surface method” to resolve this problem. This method supplies momentum to the separation part and controls flow near the wing surface by actively moving the upper surface in the direction of uniform flow; the 2D effect of this method has been demonstrated in a previous study. In this study, we successfully extended this effect to 3D wings. Upon applying the moving surface method, the NACA0006 wing achieved the largest lift-to-drag ratio improvement at an angle-of-attack of 6° and this was achieved by the Ishii wing as well. This is because, in this method, the laminar-separation bubble disappears, thus leading to a large drag reduction. In addition, as the angle-of-attack increases, differences in the 2D flow field become prominent and a strong 3D flow field appears, even when the moving surface method is not applied; at an angle-of-attack of 9°, many small vortices are generated, which complicates the flow field. The aerodynamic coefficient also varies; especially, the 3D drag coefficient is larger than its 2D counterpart. The moving surface method thus successfully suppresses 3D flow and flow separation, leading to a 2D attached flow field.</p>

  • Three-Dimensional Hypersonic Aeroheating Computations Associated with Cross-Flow Jet Interactions

    <p>Hypersonic aeroheating is one of challenging tasks in the modern Computational Fluid Dynamics (CFD), partly due to difficulties in accurate capturing of shockwaves and thermal boundary-layers, and partly due to lack of the reference data. We have tackled this problem by computationally reproducing the heating created by a hypersonic-flow/cross-flow-jet aerodynamic interaction. In the first half of this work, we surveyed both numerical flux functions and computational grids, and reached the conclusion that both AUSM<sup>+</sup>-up2 and SLAU2 successfully yielded analytical heating values with symmetry profiles over a blunt-body at Mach 8.1 (without the jet), as long as the minimum cell size was set small enough (cell-Reynolds-number being 0.32 or smaller). Then the second half was dedicated to the cross-flow-jet interaction. Using AUSM<sup>+</sup>-up2, we again succeeded in simulating the jet-interaction-induced aeroheating and pressure augmentations and their distributions, as well as complicated three-dimensional flow structures. Furthermore, a new heating mechanism not tied to pressure increase has been identified. These pieces of information are expected to serve as one of guidelines for hypersonic CFD, new insights into hypersonic flow physics, and also additional data for validation purposes.</p>
