The Buckingham Pi Theorem states that for any grouping of n parameters, they can be arranged into n-m independent dimensionless ratios (termed Π parameters). |
Buckingham's theorem provides a methodology to calculate sets of dimensionless parameters, but it says nothing about their physical significance. • If any two ... |
Π = a ap. 1 ··· ar k. Substituting equation (1) for a, we get. Π = f(a1,a2, ..., ak,ak+1, ..., an) ap. 1 ··· ar k. Using equations (3) to express ak+1,ak+2, ... |
