Correction: Aerodynamic interference on a finned slender body

Bluff Body Noise Reduction Using Aerodynamic Interference

Abstract This paper will discuss a method of bluff body noise control that utilises the phenomenon of aerodynamic interference. This technique uses a second body (not necessarily bluff) that is placed in the wake of the bluff body whose noise we wish to control. Through proper understanding of the wake dynamics, the amplitude and phase of the noise from the downstream body can be controlled so ...

Real-time Aerodynamic Sound Synthesis for Slender Objects

In this project, I explored the problem of real-time, physics-based aerodynamic sound synthesis for slender objects. It is largely inspired by the paper by Dobashi et al. [Dobashi et al. 2003]. The aerodynamic sound when we swing a slender object, such as a stick, is originated from the complex interaction between the air flow and the stick. Sufficient spatial/temporal resolution was regarded t...

Unsteady Aerodynamic Simulations of a Finned Projectile at a Supersonic Speed With Jet Interaction

Slender-Body Methods for Predicting Ship Squat

A review is made of linear slender-body methods for predicting the squat of a ship in shallow open water, dredged channels or canals. The results are summarized into a general formula based on Fourier transforms, and the method is extended to cater to stepped canals. An approximate solution for canals of arbitrary cross-section is proposed.

Nano-positioning of a slender body using thermal actuator

Current rapid development in MEMS area has opened up many possibilities in nano-technology such as nano-fabrication. Among them is nanoscale wiring by both AFM (Atomic Force Microscope) tip and laser beam. Being able to make a relatively small deflection, a micro thermal actuator can be used to control the near field optics of the beam minutely and accurately. In this project, we will investiga...
