Non-dimensionalize differential equation? - Answers

To non-dimensionalize a differential equation, you first identify the characteristic scales of the variables involved, such as time, length, or concentration. Next, you introduce non-dimensional variables by scaling the original variables with these characteristic scales. Finally, substitute these non-dimensional variables into the original equation and simplify it to eliminate any dimensional parameters, resulting in a form that highlights the relationship between dimensionless groups. This process often reveals the underlying behavior of the system and can facilitate analysis or numerical simulation.
