Gradient velocity
In continuum mechanics, the strain-rate tensor or rate-of-strain tensor is a physical quantity that describes the rate of change of the deformation of a material in the neighborhood of a certain point, at a certain moment of time. It can be defined as the derivative of the strain tensor with respect to time, or as the … See more By performing dimensional analysis, the dimensions of velocity gradient can be determined. The dimensions of velocity are $${\displaystyle {\mathsf {M^{0}L^{1}T^{-1}}}}$$, and the dimensions of … See more The study of velocity gradients is useful in analysing path dependent materials and in the subsequent study of stresses and strains; e.g., Plastic deformation of metals. The near-wall … See more Sir Isaac Newton proposed that shear stress is directly proportional to the velocity gradient: The constant of proportionality, See more Consider a material body, solid or fluid, that is flowing and/or moving in space. Let v be the velocity field within the body; that is, a smooth function from R × R such that v(p, t) is the See more • Stress tensor (disambiguation) • Finite strain theory § Time-derivative of the deformation gradient, the spatial and material velocity gradient from continuum mechanics See more WebThe velocity gradient L is defined as the gradient of the spatial description of the velocity v, i.e., (3.56) Following ( 2.17), the velocity gradient may be expressed as the sum of a symmetric tensor D and a skew tensor W, i.e., (3.57) where (3.58) D and W are called the rate of deformation tensor and the vorticity tensor, respectively.

WebThe stream gradient is the downhill slope of the channel. For example, a gradient of 10 feet per mile means that the elevation of the channel drops a total of 10 feet over 1 mile of horizontal distance traveled. Gradients are typically the lowest at a river's mouth, and highest at its headwaters.
