The chemistry and biochemistry of vanadium and the biological activities exerted by vanadium compounds.

In evolutionary multiobjective optimization, maintaining a good balance between convergence and diversity is particularly crucial to the performance of the evolutionary algorithms (EAs). In addition, it becomes increasingly important to incorporate user preferences because it will be less likely to achieve a representative subset of the Pareto-optimal solutions using a limited population size as the number of objectives increases. This paper proposes a reference vector-guided EA for many-objective optimization. The reference vectors can be used not only to decompose the original multiobjective optimization problem into a number of single-objective subproblems, but also to elucidate user preferences to target a preferred subset of the whole Pareto front (PF). In the proposed algorithm, a scalarization approach, termed angle-penalized distance, is adopted to balance convergence and diversity of the solutions in the high-dimensional objective space. An adaptation strategy is proposed to dynamically adjust the distribution of the reference vectors according to the scales of the objective functions. Our experimental results on a variety of benchmark test problems show that the proposed algorithm is highly competitive in comparison with five state-of-the-art EAs for many-objective optimization. In addition, we show that reference vectors are effective and cost-efficient for preference articulation, which is particularly desirable for many-objective optimization. Furthermore, a reference vector regeneration strategy is proposed for handling irregular PFs. Finally, the proposed algorithm is extended for solving constrained many-objective optimization problems.

Three-dimensional adaptive bisection of unstructured grids for transient compressible flow computations

On the freestream preservation of high-order conservative flux-reconstruction schemes

The flowfields around the NACA 0012 airfoil at Reynolds numbers 1×104, 3×104, and 5×104 are studied, and the predictability of aerodynamic characteristics derived from various numerical methods is examined. Two-dimensional laminar simulation, two-dimensional Reynolds-averaged Navier–Stokes simulation using the Baldwin–Lomax turbulence model, and three-dimensional implicit large-eddy simulation are employed in this study. The two-dimensional laminar and three-dimensional implicit large-eddy simulations accurately predict the separation point, and capture the characteristics of a separation bubble for each Reynolds number and each angle of attack. Nonlinearity in the lift curve is also captured in the results of the two-dimensional laminar and three-dimensional implicit large-eddy simulations. The two-dimensional Reynolds-averaged Navier–Stokes simulation using the Baldwin–Lomax turbulence model predicts the separation point nearer the trailing edge than does the two-dimensional laminar and three-dimensiona...

Computations of transonic flows over a practical wing-fuselage geometry designed for a transonic transport aircraft are carried out using three-dimensional Reynolds-averaged "thin-layer" Navier-Stokes equations. The thin-layer approximation is extended to two directions to evaluate viscous layers on both the wing and fuselage surfaces. The LU-ADI factorization algorithm is used with the implementation of new smoothing terms. Computations are done for several angles of attack with the specified Mach and Reynolds numbers corresponding to the experiment, and the comparison of the computed surface pressure to the experimental data shows good agreement. The computed results reveal the effect of the fuselage near the wing root, especially at relatively high angles of attack. It is shown that the flow pattern when a fuselage exists is quite different from that for an isolated wing. This indicates the importance of the computation over a wing-fuselage combination using Navier-Stokes equations. The computations, which uses about 700,000 grid points, requires about 5-6 h of computer time on a Japanese supercomputer for each case.
