- This is the Reynolds stress, conventionally written R _ { ij }:
- This term is known as the Reynolds stress, R _ { ij }.
- This redistributes energy among normal Reynolds stresses and thus makes them more isotropic.
- The six partial differential equations above represent six independent Reynolds stresses.
- The resulting equation contains a nonlinear term known as the Reynolds stresses which gives rise to turbulence.
- Reynolds stresses that Eclipse, which emits less smoke and odor than conventional cigarettes, is in a nascent stage.
- The left term, however, is the Reynolds stress term and is the primary production method for instability growth.
- It is observed that the wall effect increases the anisotropy of normal Reynolds stresses and decreases Reynolds shear stresses.
- An ensemble version of the governing equations is solved, which introduces new " apparent stresses " known as Reynolds stresses.
- The Reynolds stress depends on the amplitude of sound vibrations, and the body force reflects diminutions in this sound amplitude.
- In turbulence, he developed universal probability density function for turbulent velocity fluctuations, Reynolds stress and conditional Reynolds shear stresses in wall-shear flows.
- Such a modelling mainly provides the additional momentum transfer by the Reynolds stresses, although the turbulence also enhances the heat and mass transfer.
- In fact, the Reynolds stress at any given point in a turbulent fluid is somewhat subject to interpretation, depending upon how one defines the average.
- This nonlinear Reynolds stress term requires additional modeling to close the RANS equation for solving, and has led to the creation of many different turbulence models.
- This force is a function of what is known as the Reynolds stresses in turbulence-\ overline { \ rho v _ i v _ j }.
- It is believed that production and contributions to-\ overline { u'v'}, the Reynolds stress, occur during strong interactions between the inner and outer walls of hairpins.
- Due to the damping of the vertical velocity fluctuations near the wall, the Reynolds stress term will become negligible and we find that a linear velocity profile exists.
- Reynolds-stress models ( RSM ) use a different method to close the Reynolds stresses, whereby the normal stresses are not assumed isotropic, so the issue with TKE production is avoided.
- Pressure-strain interactions affect the Reynolds stresses by two different physical processes : pressure fluctuations due to eddies interacting with one another and pressure fluctuation of an eddy with a region of different mean velocity.
- For example, in order for a structure to be evolving, and hence dominant, its coherent vorticity, coherent Reynolds stress, and production terms should be larger than the time averaged values of the flow structures.
