Overview
A comprehensive CFD simulation evaluating the velocity distribution and hydraulic performance of a shell-and-tube heat exchanger used in thermal power plants. The model visualises the flow patterns at the shell inlet, at the outlet and in the middle section, in order to improve heat-transfer efficiency and minimise pressure drop.
What the model shows
- Shell inlet and outlet: the velocity field where the flow enters and leaves the shell, which is where an uneven distribution usually starts.
- Middle section: the pattern of velocity bands between the tubes along the exchanger, which governs how much of the surface transfers heat.
- Velocity scale: contours in m/s, up to about 3.2 m/s on the colour scale.
Why it matters
In a shell-and-tube heat exchanger, the flow distribution decides how much of the heat-transfer surface is actually used and how much pumping energy is lost as pressure drop. The velocity field makes weak spots visible, such as dead zones, jets and uneven loading of the tubes, so that the geometry can be improved before anything is built.
A study of this kind follows a standard CFD workflow: geometry and mesh, boundary conditions, solution, and evaluation of the results.
