چکیده

Due to the complexity of the physical mechanism of lightning and mathematical formula, Parameter range and large amount of calculation, at present the mathematical model of lightning simulation is always empirical or inconsistent with the physical properties of lightning. In order to bring down the complexity, and to advance physical properties, of the traditional lightning model the paper carries on the study of improving DBM model of lightning simulation. Firstly, the improvement of DBM model is researched. Secondly, the improved DBM model is applied to simulate a variety of effects images of lightning by computer. The research shows that the improved DBM model can cut time and space complexity, and save the workload of calculation.

Electromagnetic Field Due to Lightning Strikes to Mountainous Ground

The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...

Improvement of Methanol Synthesis Process through a Novel Sorption-Enhanced Fluidized-bed Reactor, Part I: Mathematical Modeling

In the first part of two section paper, a mathematical model of the fluidized bed reactor in the presence of in-situ water adsorbent for methanol synthesis is assessed. The bubbling two-phase regime is applied to model the fluidization concept. The binary adsorbent and catalyst particles system can be separated from each other based on their density difference. The heavy catalyst particles tend...
