In this project, steady cooling process of hot water flow in a fin pipe radiator is investigated. Due to high computational cost, only one fin pipe of radiator is simulated. Water flows in the pipe between concentric fins while free convection boundary condition is imposed at fin surface. Water enters and exits the domain with temperature equal to 327K and 326.6214K respectively.
Fin Pipe Radiator Geometry and mesh
Geometry of fluid domain is designed in Design Modeler and computational grid is generated using ANSYS Meshing. Mesh type is unstructured and element number is 624000.
Solver Configuration for Fin Pipe Radiator CFD Simulation
- Solver type is assumed Pressure Based.

Water mass flow rate at inlet is 0.0783 kg/s. Water temperature at inlet and outlet is equal to 327K and 326.6K respectively which is the result of heat transfer rate equal to 124 w for the steady cooling process. The first and the second graphs show the fins and fluid temperature as a function of position, respectively.
There is a mesh file in this product. By the way, the Training File presents how to solve the problem and extract all desired results.
