摘要：

Solutions for the three-dimensional distributions of vorticity in the wake behind localized forces moving in a viscous fluid are obtained. The forces simulate the drag, thrust, and lift forces applied on the fluid by a flying animal such as a small insect. Concentrated vortex tubes in the wake are also illustrated in a visualization experiment where a "virtual" insect is modeled using the electromagnetic method of forcing.
