Menter's Shear Stress Transport turbulence model, or SST, is a widely used and robust two-equation eddy-viscosity turbulence model used in Computational Fluid Dynamics.The model combines the k-omega turbulence model and K-epsilon turbulence model such that the k-omega is used in the inner region of the boundary layer and switches to the k-epsilon in the free shear flow.
This method can be continued indefinitely in the same way, where the order-n term consists of a harmonic term + (), plus some super-harmonic terms , +, +. The coefficients of the super-harmonic terms are solved directly, and the coefficients of the harmonic term are determined by expanding down to order-(n+1), and eliminating ...
The first approach of a compact and concise method was published by R. Doniol in 1955 [4] and involved haversines. The altitude is derived from sin ( H c ) = n − a ⋅ ( m + n ) {\displaystyle \sin(Hc)=n-a\cdot (m+n)} , in which n = cos ( L a t − D e c ) {\displaystyle n=\cos(Lat-Dec)} , m = cos ( L a t + D e c ) {\displaystyle ...
It was originally called the azimuth intercept method because the process involves drawing a line which intercepts the azimuth line. This name was shortened to intercept method and the intercept distance was shortened to 'intercept'. The method yields a line of position (LOP) on which the observer is situated. The intersection of two or more ...
The Lattice Boltzmann methods for solids (LBMS) are a set of methods for solving partial differential equations (PDE) in solid mechanics. The methods use a discretization of the Boltzmann equation(BM), and their use is known as the lattice Boltzmann methods for solids. LBMS methods are categorized by their reliance on: Vectorial distributions [1]
1975–80 statisticians R.E. Miles and P.J. Davy show that stereology can be formulated as a survey sampling technique, and develop design-based methods. 1983 R.E Miles and (independently) E.B. Jensen and H.J.G. Gundersen develop point-sampled intercept methods for inferring the mean volume of arbitrarily-shaped particles from plane sections.
There is no accepted or widely-used general term for what is termed true-range multilateration here . That name is selected because it: (a) is an accurate description and partially familiar terminology (multilateration is often used in this context); (b) avoids specifying the number of ranges involved (as does, e.g., range-range; (c) avoids implying an application (as do, e.g., DME/DME ...
The Chow test (Chinese: 鄒檢定), proposed by econometrician Gregory Chow in 1960, is a statistical test of whether the true coefficients in two linear regressions on different data sets are equal. In econometrics, it is most commonly used in time series analysis to test for the presence of a structural break at a period which can be assumed ...
