Abstract
A three dimensional electrostatic plasma particle code has been developed to investigate blob dynamics. Some results of preliminary simulations are in agreement with previous studies based on a two-dimensional reduced fluid model. When periodic boundary condition is applied in the ambient magnetic field direction, it was observed that a blob evolves to a mushroom-shaped structure. Furthermore, the relation between the observed blob propagation speed and the initial blob size is consistent with the expectation by the fluid theory.
