In the present study, a simplified, one-way coupled, Discrete Droplet Method is proposed to model multiple rain-droplet motions over the vehicle wall. The Lagrangian method is employed to track the droplet, on which four forces are considered to act,

We numerically simulated the aerodynamic noise generated from the unsteady flow around a generic model of automobile rear-view mirrors in this study. This generic model is made by cutting a hemispherical cylinder into half lengthwise, and placed on a

To reduce aerodynamic drag, reduction of skin friction is required. Vibrant flexible wall has been proposed to reduce skin friction drag for a long time. However, there are many problems for the flexible wall to get practical durability, easy mainten

To examine pressure fluctuations in the near acoustic field, the wavenumber-frequency spectrum method was applied to the flow field around a square cylinder placed near a flat plate. Since the pressure fluctuations in the near field contain both acou

In this note, we obtain a simpler expression for the constant number given by Costin–Maz’ya on the sharp Hardy–Leray inequality for a class of solenoidal (namely divergence-free) vector fields, with respect to any radial power-weighted measure.

In the previous work Hamamoto (Calc Var Partial Differ Equ 58(4):23, 2019), following from an idea of Costin–Maz’ya (Costin and Maz’ya in Calc Var Partial Differ Equ 32(4):523–532, 2008), we computed the best constant in Rellich–Leray inequ

In this paper, we show the N-dimensional Rellich-Leray inequality with optimal constant for axisymmetric and divergence-free vector fields. This is a second-order differential version of the former work by Costin-Maz’ya (Calc Var Partial Differ Equ

In this paper, we prove Hardy-Leray inequality for three-dimensional solenoidal (i.e., divergence-free) fields with the best constant. To derive the best constant, we impose the axisymmetric condition only on the swirl components. This partially comp
