There is a spherical region in the water heated up, for instance 90 degree.
The radius of this spherical region is 1 um. Thus I want to know how fast is
the water going out of this region and how fast(the speed) the water in the
peripheral region will go to fill this sperical region.
Suppose there is gold particle, which is about 1 um larg and it is 10 um
away from this hot region, the flowing water will try to push the particle
into the center. I am wondering whether there is a way to cal

I think I understand what you are trying to say.
You can write a code dealing with this kind of problem. Since it is a gold
particle, hence the problem is not axisymmetric, you need to consider 3D
effects, which is really difficult to cope with. A lot of conditions are not
defined in your statements. Hence, it is difficult for other guys to help you.
