Flow over Hills: A Large-Eddy Simulation of the Bolund Case

Jiannong Fang, Marc Parlange, Chad Higgins, Marc Diebold

Simulation of local atmospheric flows around complex topography is important for several applications in wind energy (short-term wind forecasting and turbine siting and control), local weather prediction in mountainous regions and avalanche risk assessment ...

The Effect of Scale on the Applicability of Taylor’s Frozen Turbulence Hypothesis in the Atmospheric Boundary Layer

Valentin Simeonov, Marc Parlange, Chad Higgins, Martin Froidevaux, Nikki Vercauteren, Caitlin Ellen Barry

Taylor’s frozen turbulence hypothesis is the central assumption invoked in most experiments designed to investigate turbulence physics with time resolving sensors. It is also frequently used in theoretical discussions when linking Lagrangian to Eulerian fl ...

Towards oscillation-free implementation of the immersed boundary method with spectral-like methods

Jiannong Fang, Marc Parlange, Chad Higgins, Marc Diebold

It is known that, when the immersed boundary method (IBM) is implemented within spectral-like methods, the Gibbs oscillation seriously deteriorates the calculation of derivatives near the body surface. In this paper, a radial basis function (RBF) based smo ...

A Simple Model for the Afternoon and Early Evening Decay of Convective Turbulence Over Different Land Surfaces

Marc Parlange, Chad Higgins, Daniel Nadeau, Eric Richard Pardyjak

A simple model to study the decay of turbulent kinetic energy (TKE) in the convective surface layer is presented. In this model, the TKE is dependent upon two terms, the turbulent dissipation rate and the surface buoyancy fluctuations. The time evolution o ...

Field study of the dynamics and modelling of subgrid-scale turbulence in a stable atmospheric surface layer over a glacier

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Charles Vivant Ignacio Meneveau

A field experiment – the Snow Horizontal Array Turbulence Study (SnoHATS) – has been performed over an extensive glacier in Switzerland in order to study small-scale turbulence in the stable atmospheric surface layer, and to investigate the role, dynamics ...

Albedo effect on radiative errors in air temperature measurements

Michael Lehning, Wolf Hendrik Huwald, Marc Parlange, Marc-Olivier Boldi, Chad Higgins

Most standard air temperature measurements are subject to significant errors mainly due to sensor heating by solar radiation, even when the measurement principle is accurate and precise. We present various air temperature measurements together with other m ...

Geometric Alignments of the Subgrid-Scale Force in the Atmospheric Boundary Layer

Marc Parlange, Chad Higgins, Charles Vivant Ignacio Meneveau

priori tests of subgrid-scale (SGS) models for large-eddy simulations (LES). The experimental arrangements and data collected have facilitated studies of variables such as the filtered strain rate, SGS stress and dissipation, and the eddy viscosity coeffic ...

The Effect of Filter Dimension on the Subgrid-Scale Stress, Heat Flux, and Tensor Alignments in the Atmospheric Surface Layer

Marc Parlange, Chad Higgins, Charles Vivant Ignacio Meneveau

In field experiments designed to study subgrid-scale parameterizations for large eddy simulation, the flow field is often measured and then filtered in two-dimensional planes. This two-dimensional filtering serves as a surrogate for three-dimensional filte ...
