Turbulence is a phenomenon, that despite being well known, is still not fully understood by science.
However, the objective of this report, is to show how the transistion from laminar to turbulent flow in pipes, can be modeled. Knowledge of how to model and predict the transition to turbulence is important, because this can reduce energy consumption, which is a very important area these days.
In the report, two models are presented, one more simple for introduction and one more advanced. The advanced model is built on the simpler model, and has close resemblance to what is happening in the physical world.
