Yes. Typically these types of GPU based fluid solvers use texture maps to store velocity and pressure information. (See NVIDIA’s GPU Gems paper on fluids.)
Most GPUs support 3D texture maps, and changing something like this to support 3D should be fairly trivial. From what I remember, the calculations for each dimension are identical.
