Acceleration of Bluff Body Calculation Using Mdgrape-2
نویسنده
چکیده مقاله:
Bluff body calculation was accelerated by using a special-purpose computer, MDGRAPE-2, that was exclusively designed for molecular dynamics simulations. The three main issues were solved regarding the implementation of the MDGRAPE-2 on vortex methods. These issues were the efficient calculation of the Biot-Savart and stretching equation, the optimization of the table domain, and the round-off error caused by the partially single precision calculation in the MDGRAPE-2. Finally this technique was applied to calculation of flow around a circular cylinder. The drag and lift coefficient was investigated to check the validity of the proposed method.

Acceleration of Vortex Methods Calculation Using Mdgrape-2 and Mdgrape-3: a Comparative Study
The calculation of vortex method has been accelerated by using special-purpose computers, MDGRAPE-2 and MDGRAPE-3, respectively. The similar algorithm has been implemented and the improvement in speed of MDGRAPE-2 was 100 times while MDGRAPE-3 was 1000 times faster when compared with the ordinary PC Xeon 5160(3.0GHz) for N=10. In addition, the speed of MDGRAPE-3 was 25 times faster compared wit...
متن کاملBluff 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 ...

متن کاملLinear feedback control of bluff body wakes
In this project, linear feedback control is used to modify the dynamics of fluid flows. We focus on two system identification and controller design strategies that target separated wakes behind bluff bodies. In particular, we aim to reduce the form drag and suppress the large fluctuations that typically develop in such wakes and are detrimental to efficiency and safety in a large number of indu...
