“…The authors also proposed a new IB-LBM (Suzuki & Inamuro 2011), which is more accurate for satisfying the no-slip boundary condition at a moving boundary than other IB-LBMs. The IB-LBM (Suzuki & Inamuro 2011) has already been applied to researches on flows and lift generation by the 2D symmetric flapping wing (Ota et al 2012;Kimura et al 2014) and by a dragonfly-like flapping wing-body model (Minami et al 2015).…”

The flapping flight of tiny insects such as flies or larger insects like butterflies is of fundamental interest not only in biology itself but also in its practical use for the development of micro air vehicles. It is known that a butterfly flaps downward for generating the lift force and backward for generating the thrust force. In this study, we consider a simple butterfly-like flapping wing-body in which the body is a thin rod and the rectangular rigid wings flap in a simple motion. We investigate lift and thrust generation of the model by using the immersed boundary-lattice Boltzmann method. Firstly, we compute the lift and thrust forces when the body of the model is fixed for the Reynolds numbers in the range of 50 -1000. In addition, we estimate the supportable mass for each Reynolds number from the computed lift force. Secondly, we simulate free flights when the body can only move translationally. It is found that the expected supportable mass can be supported even in the free flight except when the mass of the body relative to the mass of the fluid is too small, and the wing-body model with the mass of actual insects can go upward against the gravity. Finally, we simulate free flights when the body can move translationally and rotationally. It is found that the body has a large pitch motion and consequently gets off-balance. Then, we discuss a way to control the pitching angle by flexing the body of the wing-body model.

“…Hirohashi and Inamuro 42 have numerically examined targeting and hovering flights of a dragonfly-like flapping wing-body model (Minami et al. 43 ) by using the immersed boundary-lattice Boltzmann method. First, they simulated free flights of the model for various phase angles between the forewing and the hindwing movements and for different stroke angles between the stroke plane and the horizontal plane.…”

In the recent decades, the design and development of biomimetic micro air vehicles have gained increased interest by the global scientific and engineering communities. This has given greater motivation to study and understand the aerodynamics involved with winged insects. Dragonflies demonstrate unique and superior flight performance than most of the other insect species and birds. They are capable of sustained gliding flight as well as hovering and able to change direction very rapidly. Pairs of independently controlled forewings and hindwings give them an agile flying ability. This article presents a review of all published journal articles, listed in the Thomson-Reuters Web-of-Science database (1985–2018), that are related to the flight aerodynamics of dragonflies or micro air vehicles that biomimic them. The effects of dragonfly wing motions and interactions (between forewing and hindwing) that are necessary to generate the appropriate aerodynamic forces in different flight modes are described. The associated power requirements of these modes are also addressed. This article aims to provide a valuable reference to the aerodynamic design and control of dragonfly-inspired biomimetic micro air vehicles.

“…In this paper, the Multi Direct Forcing Method (MDFM) proposed by Wang et al [28] and later coupled with LBM by Suzuki and Inamuro [29] is employed, which improves accuracy of the no-slip boundary condition by solving the body force iteratively. It has been validated with experimental and theoretical results [29,30], and was used in the simulation of butterfly-like and dragonfly-like flapping wings [31].…”

At low terminal Reynolds numbers Re = 2 − 10, there are multiple asymmetrical principal movement states for the sedimentation of a pair of particles in a channel filled with a viscous fluid. The main emphasis of this work is to investigate the formation process of these states and the effect of the natural rotation on the process when particles are released symmetrically. The flow field around each particle is fully resolved with an Immersed Boundary Method (IBM) coupled with the Cascaded Lattice Boltzmann Method (CLBM). An improved algorithm is developed to couple IBM with CLBM which can fully exploit the Graphic Processing Unit (GPU) for parallelisation. The collision between particles is handled with the Discrete Element Model (DEM). The approach is validated considering the sedimentation of a single particle released asymmetrically and also the Drafting-Kissing-Tumbling (DKT) problem of two
