As Spice is marketed as a cannabis alternative and binds to the same cannabinoid receptors in the brain as marijuana, you would expect it to have similar effects.

It has long been assumed that the spreading rate of the wake in the self-similar regime is independent of the details of the body generating the wake, being dependent only on the total drag (or momentum deficit).Cited by: A Numerical Study of Self-Similarity in a Turbulent Plane Wake Using Large-Eddy Simulation.

It has long been assumed that the spreading rate of the wake in the self-similar regime is. Abstract. One of the most widely accepted ideas in turbulence theory is that the large-scale structures in turbulent shear flows forget how they are generated so that all flows of a particular type asymptotically evolve to a single universal state.

It is shown here, usingthe temporally evolvingw ake as an example, that the governing equations for the two-point velocity correlations have self Cited by: 2.

However, no attempt was made to test the hypotheses using data from these non- homogeneous flows. Here, data from two Direct Numerical Simulations of the temporally evolving wake (Moser and Rogers, ) are Direct simulation of a self-similar plane wake book to test the similar hypothesis for the two-point correlations in this software-comparativo.com by: 1.

Advances in Turbulence 3: Proceedings of the Third European Turbulence Conference Stockholm, July[Arne V Johansson; P Henrik Alfredsson] -- The book covers the following main topics: turbulence structure, transition, dynamical systems in relation to transition, turbulent combustion and mixing, turbulence affected by body forces.

Results are presented for plane channel flow, and both zero and adverse pressure gradient boundary layers. Favorable results for the anisotropies in the Reynolds stresses are obtained by the new model as validated by comparisons against direct numerical simulation (DNS) and experimental data.

Washington, DC: The National Academies Press. doi: / The presence of flow reversal is required to produce an absolute instability in the self-similar wake, but such a velocity profile can not exist far behind the ship.

We note that, if such a profile were present, it would remain. Besides, the upper boundary is subject to the slip condition, meaning no flux and vertical velocity gradient in this plane. The direct simulation of the flow over a rough ground with high Reynolds number is computationally unacceptable, so in the lower boundary, the Moeng’s wall model is introduced to estimate the surface stress on the basis Author: Xu Ning, Decheng Wan.
