Atmospheric Electricity Modeling and Corona Dischargement Motor Design

Paper | PPT for Thesis Defense

Abstract: Based on the observation data and theoretical modeling of atmospheric electric field, this paper explains the formation reasons of atmospheric electric field.A simple model of atmospheric electric field and magnitude of field intensity are obtained. And considering the influence of thunderstorm weather on atmospheric electric field, on the model. Make optimizations. Based on this, a motor based on corona discharge principle is designed to analyze the ionic wind phenomenon of corona discharge. Numerical simulation exploration. By controlling the number of stator, the size of air gap and the deviation Angle between stator and axis, a better theoretical result is obtained. The body device utilizes the atmospheric electric field in the natural environment.

Design of seismograph based on raspberry PI platform and the practice of calculating station clock difference and Green's function by cross correlation function

Report | Github

Abstract: In this paper, a simple seismograph is built by using raspberry PI platform, 3D geophone and analog-to-digital conversion chip. In the field data measurement, the station clock difference between the homemade seismograph and the professional seismograph with GPS automatic timing function is obtained by using cross-correlation function. Furthermore, the green's function between the station pairs is obtained by using the cross-correlation technique to deal with the noise records of three professional seismographs in the same.
