This repository solves heat transfer problems in pipe flows. The user may specify a variety of geometries, flow conditions, and thermal boundary condition. The output includes the wall temperature, bulk fluid temperature, and heat flux distributions in the streamwise direction. A description of the main settings is given below.
| Setting | Options | Description |
|---|---|---|
| fluid | 'air', 'water', 'user defined' | Defines the fluid object for property look-up in Cantera. Fluid properties may be specified manually if 'user defined' is chosen. |
| shape | 'round', 'rectangle' | Defines the shape of the pipe wall. |
| BC | 'prescribed temp', 'conjugate' | Defines the type of boundary condition used for the internal fluid. |
| wall_conduction | 'thin', 'thick' | Defines the type of discretization used in the solid domain. This setting only applies when BC = 'conjugate'. |
| transient | true, false | Toggles steady/unsteady analysis. This setting only applies when BC = 'conjugate'. |
| radiation | true, false | Toggles radiation effects on the outer pipe wall. This setting only applies when BC = 'conjugate'. |
| write | true, false | Toggles option to write data to text file. |
You will need MATLAB to run this code as well as a compatible version of Cantera in order to support fluid property look-ups. Alternatively, you may skip the Cantera installation, but be sure to set the "fluid" variable to 'user defined' or else the code will not run. In this case you will be prompted to enter the fluid properties manually. Once all of the code in the repository have been downloaded to a single directory, the "main.m" script should be executed.
