Abstract Direct numerical simulation (DNS) of transition over a hypersonic lifting body model HyTRV developed by China Aerodynamics Research and Development Center is performed. The free-stream parameters are: the Mach number 6, unit Reynolds 10000/mm, temperature 79 K, angle attack 0, wall 300 K. Weak random blowing-and-suction perturbations in leading range are used to trigger transition. A h...

The hyperbolic wave equation of heat conduction with respect to Christov's formulation is utilized the Streamline- Upwind-Petrov-Galerkin method in space and Θ, Houbolt, linear acceleration, Wilson-Θ Newmark methods time. derivation this its matrix are shown. A 2D transient finite element simulation a generic asperity an infinite line source interface, either as flux density q̇ or temperature di...

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...

ied in twelve patients undergoing taparotomy without liver disease. Liver scintigrams were obtained following injection of tracer doses of 198Aucolloj@ into a mesenteric vein and corn pared with repeat scintigrams obtained follow ing i.v. injection of ssmTc.rnicroaggregated albumin. Particularly from subdivisions of the superior rnesenteric vein, portal vein blood is directed predominantly to t...

STREAMLINE aims for improving the overall workflow of big data analytics systems. For this goal, it combines research in different areas to reduce the complexity of the work with data at rest and data in motion in a unified fashion. As a foundation STREAMLINE offers a uniform programming model on top of Apache Flink, for which it drives innovations in a wide range of areas, such as interactive ...

Introduction: Neighborhood tractography offers the potential to improve the reliability and reproducibility of automated white matter pathway extraction and associated measurements of connectivity and tract integrity. Neighborhood tractography frameworks have been proposed for local tractography methods, particularly those based on streamline, or probabilistic streamline algorithms [1,2]. In th...

Currently, there are no methods of visual analysis for ensemble vector fields (EVF) that provide identification of flow trends and general flow similarity over the extent of transport across ensemble members. Finite-time Variance Analysis (FTVA) provides flow structure information only on particle distributions at the termination of streamline integration. In this paper, we first present a flow...
