| Project Objectives | There are a few recent studies about the prediction of the friction
factor of coils. The most used relationship it was developed in 1967
by Mori and Nakayama in terms of the Reynolsd Number (Re) and the
Curvature Number (Cu). The main goal of this project is to find a mathematical correlation to predict the friction factor of coils built with smooth pipes in terms of the Reynolds Number and the Curvature using the perturbation theory. |
| Required skills | Academic and research independence Knowledge of the fluid mechanics theory Statistical methods of data analysis Instrumental methods Computational data analysis methods |
| Techniques to be used | Measurements of pressure looses in pipes Statistical analysis of experimental data Numerical regression techniques |
| Schedule of Activities | Selecting and setting up the experimental equipment (1 week) Find a mathematical relationship between the head looses and the friction factor in smooth straight pipes (3 weeks) Build the coils (at least 10) using the smooth material (2 weeks) Find the correlation between head looses, curvature and friction factor (4 weeks) Write the technical report (2 weeks) |
