Particle methods for direct numerical simulations of three - dimensional wakes †
In this paper we describe recent advances in the development of particle methods for the direct numerical simulations of three-dimensional wakes. Both body-fitted and immersed boundary techniques are considered. The accuracy and numerical cost of the proposed numerical methods are discussed on the benchmark cases of a flow past a cylinder and of a vortex ring impinging on a cylinder. PACS numbe...
متن کاملSimulation and control of three-dimensional wakes
We illustrate the problem of wake optimization on two examples. In the first example, the destruction of trailing vortices, we show that stochastic optimization is a flexible tool to identify vortex systems enhancing natural instabilities. In the second example, the problem of drag reduction in a cylinder wake, a priori information on the flow dynamics is highly desirable and we give some preli...

THREE-DIMENSIONAL WAKES IN LINEARLY STRATIFIED LIQUIDS by Philip J. Stockhausen, Charles B. Clark Submitted to the Department of Civil Engineering on May 26, 1966, in partial fulfillment of the requirements for the degree of Master of Science. The wake and the zone of turbulently mixed fluid behind a threedimensional body in a liquid with a linear density gradient were studied. The objective of...

مدلهای گارچ در فضاهای هیلبرت پایان نامه حاضر شامل دو بخش می باشد. در قسمت اول مدلهای اتورگرسیو تعمیم یافته مشروط به ناهمگنی واریانس در فضاهای هیلبرت را معرفی، مفاهیم ریاضی مورد نیاز در تحلیل این مدلها در دامنه زمان را مطرح کرده و آنها را مورد بررسی قرار می دهیم. بر اساس پیشرفتهایی که اخیرا در زمینه تئوری داده های تابعی و آماره های عملگری ایجاد شده است، فرآیندهایی که دارای مقادیر در فضاهای ...
15 صفحه اولIntermittency and coherent structures in the two-dimensional inverse energy cascade: comparing numerical and laboratory experiments.
We study the internal intermittency in the inverse energy cascade and in the condensation regime of two-dimensional turbulence, using physical and numerical experimental approaches. The analysis confirms that the velocity increments have nearly Gaussian distributions at all scales in the inverse cascade regime; it moreover shows that, in the condensation regime, the probability distribution fun...
