Books in the Elements in Aerospace Engineering series

This Element addresses the aerodynamics, aeroelasticity, geometry, stability and dynamics of flexible flapping wings in the insect flight regime. It highlights distinct features and issues related to wing-wing interactions, contrast aerodynamic stability between rigid and flexible wings and the implications of wing aspect ratio.

Gas-particle flows became relevant in Aerospace Engineering owing to small solid particle additives to alleviate acoustical instabilities in solid propellant rocket motors, thereby motivating the study of a variety of nonlinear and linear waves. Emphasis is placed on fundamental aspects of the relaxation nature of the flow processes.

A unified computational fluid dynamics framework from rarefied to continuum regime is presented in this Element. This framework is based on the direct modelling of flow physics in a discretized space. The mesh size and time step are used as modelling scales in the construction of discretized governing equations.
