TLDR
In this article, a numerical code for the flowfield simulation of low-power applied-field magnetoplasmadynamic (AFMPD) thrusters is proposed to deal with a complicated mixture of the induced and applied magnetic fields, which will lead to a combination of the self-field, swirl, Hall, as well as electrothermal acceleration.Abstract:
In spite of many experimental studies of low-power applied-field magnetoplasmadynamic (AFMPD) thrusters, thrust efficiencies of the past thrusters are very low. Hence, drastic improvement in thrust performance is required for AF-MPD thrusters to compete against other types of electric propulsion in a moderate power regime around 10 kW. For the optimization of AF-MPD thrusters, a numerical code for the flowfield simulation is now under development. A preliminary result shows that the code can deal with a complicated mixture of the induced and applied magnetic fields, which will lead to a combination of the self-field, swirl, Hall, as well as electrothermal accelerations.read more

Active control of flame oscillation in lean premixed burners by phase- controlled sound waves
TL;DR: In this article, the phase-controlled sound wave was used to actively control the flame oscillation in the experimental lean premixed methane burner by sensing the preferential frequency and generating the sensor-triggered sound waves with fixed optimum phase difference with the flame.
Large Eddy Simulation of a High Subsonic Jet and Noise Generation
TL;DR: In this paper, high subsonic jets were computed by using compressible Large Eddy Simulation (LES), wherein the inflow forcing or disturbance added in the infow shear layer was incorporated.
