Book Synopsis A Priori Study of Subgrid-scale Flux of a Passive Scalar in Isotropic Homogeneous Turbulence by :
Download or read book A Priori Study of Subgrid-scale Flux of a Passive Scalar in Isotropic Homogeneous Turbulence written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We perform a direct numerical simulation (DNS) of forced homogeneous isotropic turbulence with a passive scalar that is forced by mean gradient. The DNS data are used to study the properties of subgrid-scale flux of a passive scalar in the framework of large eddy simulation (LES), such as alignment trends between the flux, resolved, and subgrid-scale flow structures. It is shown that the direction of the flux is strongly coupled with the subgrid-scale stress axes rather than the resolved flow quantities such as strain, vorticity, or scalar gradient. We derive an approximate transport equation for the subgrid-scale flux of a scalar and look at the relative importance of the terms in the transport equation. A particular form of LES tensor-viscosity model for the scalar flux is investigated, which includes the subgrid-scale stress. Effect of different models for the subgrid-scale stress on the model for the subgrid-scale flux is studied.

Book Synopsis Analysis of Intermittency in Turbulent Flows by Way of Higher-order Spectral Moments by : Samuel Lortie
Download or read book Analysis of Intermittency in Turbulent Flows by Way of Higher-order Spectral Moments written by Samuel Lortie and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The analysis of turbulence by way of higher-order spectral moments is uncommon, despite the relatively frequent use of such statistical analyses in other fields of physics and engineering. In this work, higher-order spectral moments are used to investigate the internal intermittency of the turbulent velocity and passive scalar (temperature) fields. This research first introduces the theory behind higher-order spectral moments as they pertain to the field of turbulence. Then, a short-time-Fourier-transform-based method is developed to estimate the higher-order spectral moments and provide a relative, scale-by-scale measure of intermittency. Experimental data are subsequently analysed and consist of measurements of homogeneous, isotropic, high-Reynolds-number, passive and active grid turbulence and wall-bounded turbulence (fully developed turbulent channel flow) over Taylor microscale Reynolds numbers between 35 and 731. Emphasis is placed on third- and fourth-order spectral moments using the definitions formalised by Antoni (2006), as such statistics are sensitive to transients and provide insight into deviations from Gaussian behaviour in grid turbulence. The higher-order spectral moments are also used to investigate the Reynolds and Péclet number dependence of the internal intermittency of velocity and passive scalar fields, respectively. The results demonstrate that the evolution of higher-order spectral moments with Reynolds number is strongly dependent on wavenumber. Additionally, the relative levels of internal intermittency of velocity and passive scalar fields are compared and a higher level of internal intermittency in the inertial subrange of the scalar field is consistently observed whereas a similar level of internal intermittency is observed for the velocity and passive scalar fields for the high-Reynolds-numbers-cases as the Kolmogorov length scale is approached. Finally, higher-order spectral moments are shown to display increased levels in the near-wall region of a wall-bounded (channel) flow. The increased intermittent activity is believed to be caused by the presence of coherent structures in wall-bounded flows"--
