Gas cools and falls toward the black hole at an accelerating rate, causing the black hole to increase the output of its jets, which produce cavities and drive the turbulence
in the gas.
The original equations written for each component of the Reynolds stress were reduced to their general form in terms of the turbulence
energy and its dissipation rate with additional effect of the particulate phase.
McKeon said that they now have a low-cost way of looking at the 'skeleton' of wall turbulence
, explaining that similar previous experiments required the use of a supercomputer.
Moderate or greater turbulence
has a specific definition in aviation.
To this purpose the Reynolds-averaged Navier-Stokes (RANS) equations govern the transport of the averaged flow quantities, with the whole range of the scales of turbulence
So although Winning in Turbulence
may not have the depth of other business books, it is still a helpful tool for busy executives faced with hard decisions.
caused by nearby storms or low pressure systems is much easier than knowing when CAT might hit.
This report, from NASA and the National Research Council, assesses federal wake turbulence
research and development programs to consider whether goals to address the issue of wake turbulence
as a barrier to increased air traffic are well-defined, whether there are any deficiencies in them, and what the roles of federal agencies should be.
Among various CFD influential factors, proper selection of a turbulence
modeling method is a key issue that will directly affect the simulation accuracy and efficiency.
It is shown that the model explains the marked difference between the turbulence
regimes on the cyclonic and anticyclonic sides of the stream.
caused minor injuries to three crew members, reported Iceland Review.
However, splashing and turbulence
during the initial stages of filling can be excessive due to the high speed of the rotation of the mold.
