  • Computational Electromagnetic-Aerodynamics

    Computational electromagnetic-aerodynamics (CEA) or computational electromagnetic fluid dynamics is an interdisciplinary science. The fundamental governing equations are the Boltzmann and Maxwell equations for describing the plasma dynamics in flow fields. The system of equations solves distribution functions of space and velocity in time that is a seven- dimensional formulation, and solutions to the governing equations are probabilistic. In cases the collision mean-free path is much greater than the characteristic scale of the studied phenomenon, the plasma can be approximated as collisionless and the Vlasov approximation is valid. The chapter discusses unique feature of diffusion in plasma and additional and uncommon mechanisms such as pressure, thermal, field force diffusion other than the electromagnetic field. In summary, most adopted numerical algorithms in CEA are shared with CFD, especially for thermally excited ionizations. These numerical procedures are built on either the classical ADI scheme for finite- difference approximation or the Gauss-Siedel relaxation for finite-volume approach.

  • Joule-Heating Actuators

    Many exciting innovations were put forth in areas of Magnetohydrodynamics (MHD) propulsion, remote energy deposition for drag reduction, plasma actuator, radiation-driven hypersonic wind tunnel, sonic boom meditation, and enhanced plasma ignition and combustion stability. The plasma heating consists mainly of Joule-heating and stochastic heating; the latter however is nearly negligible except in an oscillating plasma sheath. The Joule-heating concentrates within the cathode layer and is a rather small but effective spatial heat source to the surrounding gas stream. The interactions between aerodynamics and the surface electron impact discharge have been simulated by computational electromagnetic aerodynamics using a multifluid, drift-diffusion weakly ionized gas model. Surface pressures were recorded for a variety of magnetic field strengths and electric currents for all combinations of electrode and magnet polarity. Small perturbations in a boundary layer by a shallow bump can produce a profound change to the dynamic structure of a flow field.

  • Computational Fluid Dynamics

    A wide range of coordinate transformation techniques, computational grid generations, and different grid topologies have also been devised to accommodate complex aerodynamic configurations. This chapter focuses on computational fluid dynamics and the electromagnetic-aerodynamics interactions are addressed. The fundamental principle of Newtonian mechanics is the conservation of mass, which means that the exchange of mass and energy is not considered. Classic viscous-inviscid interactions without flow separation are noted on leading edges of an aerodynamic shape from vorticity and Mach wave interactions. The self-sustained oscillation is evident and the magnitude of the pressure pulsation is about 17 times of the free stream value. Vortex bifurcations at high incidence drastically affect aerodynamic behavior embracing asymmetric forebody vortex formation, vortex breakdown, and unsteady asymmetric force generation. Laminar-turbulent transition is one of the most challenging of fluid dynamics phenomena because it is a nonlinear and time- dependent fluid dynamic bifurcation and deeply rooted in hydrodynamic stability.

  • Lorentz-Force Actuator

    This chapter discusses the remote energy deposition through plasma injection or a microwave beam, and the resulting stagnation point heat transfer mitigation. An outstanding feature of plasma in an extremely strong externally applied magnetic field is that the magnetic lines are frozen in charged particle motion. An idealized upper theoretical limit for stagnation point heat transfer mitigation is demonstrated by Gaitonde and Poggie by solving the MHD equations with a value of electric conductivity determined by a square power-law dependence to local temperature. The computational results produce only the periodic electrostatic force of the direct current discharge (DBD), which is the driving mechanism of the electric wind, but the experimental data are the measured resultant force through the interaction of the charged and neutral particles. A numerical simulation of micro jets will definitely open a new avenue for research into enhancing combustion stability, plasma-assisted ignition, and wound pathologies.

  • Ionization Processes

    The ionization process of atoms or molecules is through energizing the electrons causing them to leave stable orbit revolving around the nucleus and becoming free-moving charges. The main mechanisms for ionization consist of thermal, electron impact, chemical reactions, photoionization, and microwave or electron cyclotron resonance. This chapter describes the ionization that focus on the basic mechanisms of photoemission, thermal, and electron impact discharges. The equilibrium ionization of the mixture of electrons, ions, and neutral particles can be analyzed by the law of mass action and the electronic partition function. Under gas discharge conditions, ionization by electron impact dominates over the photoionization because the cross sections of photoionization close to the ionizing threshold are rather high. The chapter provides Saha equation of ionization. An important parameter for the ionization rate is the mean free path of the gas medium and is ultimately related to the collision cross section.

  • Magnetohydrodynamics Formulation

    Magnetohydrodynamics (MHD) was originally applied mostly to astrophysics and geophysics. In MHD the motion of collective charged particles is described by an electrically conducting fluid with the usual fluid dynamic variables of velocity, density and pressure or temperature. The interactions of fluid dynamics and electromagnetics are exclusively derived from the magnetic flux density. This chapter presents a systematic derivation of the governing equations of MHD. The first and foremost assumption for MHD formulation is that the physical phenomena are describable by macroscopic scales or in the framework of continuum mechanics. The electromagnetic waves are compound waves for which the compression and rarefaction components can coexist and the direct consequence of the nonconvexity of the ideal MHD equations. The chapter discusses additional computational simulations to show the lack of detailed plasma composition that is required for determining electric conductivity of plasma in the MHD formulation.

  • Computational Electromagnetics

    Computational simulations of electromagnetic-aerodynamic interactions must be built on the capability of computational electromagnetics (CEM) that has a tier structure for solving the Maxwell equations. This chapter focuses on introducing the characteristic-based finite-volume and finite-difference methods. The multidimensional equations are required to be split into multiple one-dimensional space-time formulations. The finite size of computer memory compels all computations to be conducted in a truncated computational domain, thus introducing an artificial boundary to the numerical simulation. Numerous boundary conditions have been developed to annihilate the nonphysical reflected waves from the numerical boundary. For simulating wave motion, the compatibility condition at any point in space is described by the split flux vector. The finite-volume approximation satisfies the governing equation over an elementary volume that bounded by six control surface perpendicular to three coordinates. The computational efficiency of a numerical procedure is another consideration for selecting simulation tools.

  • Electromagnetic Wave Propagation and Scattering

    The electromagnetic field of a dipole decays rapidly with distance to exhibit clear distinctive structures of the far field form the near field. The wave reflection feature is exemplified by the radar cross section (RCS) of a reflected wave from electric scatterers. This chapter focuses on all these behaviors of propagating electromagnetic waves. Electromagnetic energy transmission is a very important subject in microwaves for telecommunication and plasma diagnostic applications. The measured phase shift depends only upon the electron density, but the attenuation of wave amplitude depends on both the electron density and the collision frequency for momentum transfer. In the plasma domain, the microwave magnetic component exhibits a significant distortion and remerges at the exit interface to show attenuation in wave amplitude. The concurrent computational capability and the general curvilinear coordinate transformation open the possibility for CEM of complex electrical scattering.
