Q Describe what you do in your current work situation? A I use computers to simulate fluid flow, heat transfer and mixing. I work for a construction company and sometimes we build things that are very complex. Because they are complex we need to model the objects in a computer to see what will happen when we actually build it. An example is when we model the fluid flow through all of the pipes that you see at oil or gas refineries. Another example is to model the flow of the water in the locks in the new Panama Canal. These are so big that we need to model them first to make sure that they work before actually building them.
