However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence create a very complex phenomenon. Physicist Richard Feynman described turbulence as the most important unsolved problem in classical physics.
Here's what to know about why and how to stay safe. ... Is turbulence dangerous? It doesn't have to be. Even as severe turbulence increases, "it's going from being really, really rare to still ...
This explains why updrafts underneath the base of a cumulonimbus are often laminar. This phenomenon is well known by glider pilots. [16] (see below). The phenomenon is enhanced under the weak echo region of a supercell thunderstorm that is extremely dangerous. At approximately 4 kilometres (13,000 ft) these smooth updrafts become suddenly very ...
Turbulence or pockets of disturbed air can have many causes, most obviously the unstable weather patterns that trigger storms, according to an industry briefing by planemaker Airbus. The resulting ...
In computational fluid dynamics, the k–omega (k–ω) turbulence model [10] is a common two-equation turbulence model that is used as a closure for the Reynolds-averaged Navier–Stokes equations (RANS equations). The model attempts to predict turbulence by two partial differential equations for two variables, k and ω, with the first ...
The death of a British man and injuries impacting dozens of other people aboard a Singapore Airlines flight that hit severe turbulence Tuesday highlighted the potential dangers of flying through ...
Clear-air turbulence is not possible to detect with the naked eye [7] and very difficult to detect with a conventional radar, [8] with the result that it is difficult for aircraft pilots to detect and avoid it.
The turbulent Schmidt number is commonly used in turbulence research and is defined as: [3] = where: is the eddy viscosity in units of (m 2 /s); is the eddy diffusivity (m 2 /s).; The turbulent Schmidt number describes the ratio between the rates of turbulent transport of momentum and the turbulent transport of mass (or any passive scalar).
