We consider a nonconforming streamline-diiusion nite element method for solving convection-diiusion problems. The theoretical and numerical investigation for triangular and tetrahedral meshes recently given by John, Maubach and Tobiska has shown that the usual application of the SDFEM gives not a suucient stabilization. Additional parameter dependent jump terms have been proposed which preserve...

We present a new method for extracting and quantifying separation and attachment points from 2D blood flow field images. The new technique calculates the signed streamline curvature at each point of the field which is a first order rather than second order quantity in a velocity field, and then searches for zero crossings of this function. Additional constraints based on the evaluated Jacobian ...

Abstract Previous studies (Watt et al. in J Eng Math 75(1):1, 2012; Cartwright and Falle 115(1):157, 2019) have shown that a streamline based approach to modelling of steady state detonations can produce good results for rate laws which maximal reaction at the shock. In this paper we consider Variational Streamline Approximation (VSA) introduces curvature. Comparing with Direct Numerical Simula...

Flow computations around two element and three element con gurations are pre sented and compared to detailed experimental measurements The k v model has been applied and the ability of the model to capture streamline curvature e ects wake boundary layer con uence and laminar turbulent transition is discussed The numerical results are compared to experimental datasets that include mean quan titi...

Streamline methods have received renewed interest over the past decade as an attractive alternative to traditional finite-difference (FD) simulation. They have been applied successfully to a wide range of problems including production optimization, history matching, and upscaling. Streamline methods are also being extended to provide an efficient and accurate tool for compositional reservoir si...

Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...
