Three-dimensional unsteady model of arc heater plasma flow

چکیده
Arc jets are unique facilities used to evaluate the performance of Thermal Protection Systems (TPS) for hypersonic vehicles. They produce high pressure and enthalpy plasma flow simulate extreme heat encountered during atmospheric entry. The constricted arc heater part an jet increases test gas temperature by Joule heating. This study details development three-dimensional unsteady analysis tool, ARCHeS (ARC Heater Simulator). Coupled Navier-Stokes, radiative transfer Maxwell equations yield current density, magnetism, radiation, field solutions. present work constitutes first demonstration simulation that captures kink instabilities electric arc. It is found attachment mainly driven upstream instabilities.

Three-dimensional Temporal Instability of Unsteady Pipe Flow
In this paper, 3-dimensional linear instability analysis has been carried out for unsteady pipe flow. An inflectional velocity profile from [2] has been considered and the stability analysis of it has been carried out for (axisymmetric mode) and 0 = n 2 & 1 = n . It was revealed that the profile is unstable for both axisymmetric and non-axisymmetric modes. The mode 1 = n was observed to be most...
متن کاملNumerical Simulation of Three-Dimensional Unsteady Flow past Ice Crystals
The unsteady flow fields around falling columnar ice crystals, hexagonal ice plates, and broad-branch crystals are simulated by numerically solving the time-dependent Navier–Stokes equations appropriate for these geometries in the primitive equation form. A predictor–corrector method and a quadratic interpolation for convective kinematics (QUICK) scheme are applied on nonuniform grids to determ...
متن کاملThree-dimensional unsteady incompressible flow computations using multigrid
We apply a robust and computationally efficient multigrid-driven algorithm for the simulation of time-dependent three-dimensional incompressible bluff body wakes at low Reynolds numbers (Re less than or equal to 350). The computational algorithm combines a generalized time-accurate artificial compressibility approach, a finite-volume discretization in space, and an implicit backward discretizat...
