An Estimation of the Heat Load Distribution on the Divertor Target Using the CSD Model
Contributions to Plasma Physics, EarlyView.ABSTRACT Handling the heat load on the divertor target is a critical issue in the design of fusion reactors. Estimating the heat load, supported by computationally efficient simulations with varying design parameters, provides valuable input to high‐level design discussions and the development of design guidelines.

First SOLPS‐ITER Simulation Study of Japanese DEMO on Leakage of Seeded Ar Impurity
Contributions to Plasma Physics, EarlyView.ABSTRACT For JA DEMO, one of the grand challenges is efficiently handling the extreme power loads onto plasma‐facing components, particularly the divertor targets. Impurity seeding is an essential strategy for increasing the radiation losses and thereby reducing the heat load on the targets.

MHD stagnation-point flow [PDF]
, 2013 The flow near a stagnation-point is a fundamental topic in fluid dynamics and it has been studied by several researches during the past decades because of its relevant applications. In this Thesis we investigate the influence of the electromagnetic field on the stagnation-point flow of a Newtonian or a micropolar fluid.

Stagnation Point Combustion of a Monopropellant
AIAA Journal, 1981The steady-state stagnation point transport and reaction equations describing premixed monopropellant combustion have been investigated approximating the chemical processes by an endothermic solid-phase pyrolysis and a one-step exothermic unidirectional gas-phase reaction.

MIXED CONVECTION AT A STAGNATION POINT
The Quarterly Journal of Mechanics and Applied Mathematics, 1995Summary: We are concerned with the mixed convective flow at a two-dimensional stagnation point on a heated horizontal boundary. The forced flow may be a stagnation-point flow of either forward or rear type, and the free convective element is due to a pressure gradient that is induced by temperature variations along the boundary.

Stagnation‐point Flow in Magnetohydrodynamics
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1967AbstractThe inviscid three‐dimensional stagnation‐point in magnetohydrodynamics is investigated in full generality. The analytic character of the flow depends on just two parameters, one of which characterizes the streamline pattern on the body and the other the effective interaction of the electromagnetic field. The pattern, according to linear terms,

Blood rheology near a stagnation point
Biorheology, 1982Blood rheology at a stagnation point is studied in views of microhemorheology. Special emphasis is put on the effect of both non-Newtonian and unhomogeneous properties of blood on the fine structure of blood flow impinging on the wall. It is shown that “non-flow” region exists just at the stagnation point due to the non-Newtonian viscosity when its ...

AN UNSTEADY STAGNATION-POINT FLOW
The Quarterly Journal of Mechanics and Applied Mathematics, 1989We consider the oscillatory flow at a two-dimensional stagnation point. We show, following the initiation of the motion, that the solution always develops a singularity at a finite time, and we discuss the implications of this for the flow over a cylinder which performs transverse harmonic ...

Unsteady stagnation point flow
Applied Scientific Research, 1972In this paper we consider the changes in the two-dimensional stagnation point flow against a plane wall when the wall is impulsively set in motion in its own plane. In particular a solution which describes the final approach to the ultimate steady state is determined.
