9313712 Gombosi Dynamics of Cometary Environments. Dr. Gombosi will continue his theoretical studies of dusty cometary gas flows and the solar wind interaction with comets. Dr. Gombosi is participating in the development of a new solution, adaptive, multidimensional, numerical methodology. He will apply this new technology to multiscale phenomena in comet environments. The major advance of the proposed over previous models is the use of adaptively refined meshes, so that high resolution can be achieved in areas such as the edges of active regions, the sonic transition region in cometary jets, cometary bow shocks, the diamagnetic cavity boundary, or the very thin recombination layer near the contact surface.

9313712彗星环境的Gombosi动力学。Gombosi博士将继续他关于尘埃彗星气体流动和太阳风与彗星相互作用的理论研究。Gombosi博士正在参与开发一种新的解决方案，一种自适应的多维数值方法。他将把这项新技术应用于彗星环境中的多尺度现象。与以前的模型相比，所提出的模型的主要进步是使用了自适应细化网格，因此可以在活动区域边缘、彗星喷流中的声波过渡区域、彗星弓形激波、抗磁腔边界或接触面附近的极薄复合层等区域实现高分辨率。
