This anisotropic behaviour is different from that observed in sheared homogeneous turbulent flows, where high transverse derivative moments are generated, but longitudinal moments almost maintain the isotropic turbulence values. Apart from the behaviour of the energy gradient transients, the results also ...
Positive displacement flow meters are used for measurements when straight pipe is not available or as a replacement for turbine flow meters and paddle wheel sensors when there is too much turbulence in the flow.Unlike gear type positive displacement flow meters, screw flow meters have a set of ...

The trading volume, kinetic energy, and opportunities that exist in the foreign exchange market are huge. Some people think that it is closest to the perfect market: all traders from individuals to big banks trade under the same terms and requirements, get the same information, and the market ...
The fin in the cold plate creates turbulence that reduces thermal resistance. Aluminum vacuum brazed cold plates come in sizes ranging from a few inches up to several hundred inches. Cold plates can be mounted on the laser and receive cooling liquids from a chiller. The heated liquid from ...
What is the difference between \mu_s and \mu_k? Which of the two is bigger? Why doesn't a gyroscope fall over? What is the difference between magnetic field and magnetic force? What is elastic after effect? What causes turbulence in fluid flow? Why is an uphill road wider than down...
The most common one is the k-ε turbulence model (one of many RANS turbulence models). This model is often used in industrial applications because it is both robust and computationally inexpensive. It consists of solving two additional equations for the transport of turbulent kinetic energy k ...
The nice thing about this latter equation is that the first equation is basically just a formula for and so can be dropped, leaving us with This equation now admits a two-parameter family of scale invariances for , where we use to ednote the coordinate. It also inherits an energy conse...
Van Gogh's 'Starry Night' contains surprisingly accurate physics — suggesting he understood the hidden 'dynamism of the sky'A new analysis of the brushstrokes and colors in Vincent van Gogh's famous painting Starry Night reveals a striking similarity to "hidden turbulence" in Earth's atmosphere...
The design of plate and frame heat exchangers offers a large heat transfer area, high turbulence, and increased resistance to fouling. As a result, they achieve higher overall heat transfer coefficients and efficiencies compared to tubular heat exchangers. However, the fluids experience a high-pressu...
