Equações adimensionais para MD | ||
m' = adimensional | ||
m* = valor dimensional de referência | ||
[] vetor | ||
|
||
m' = m/m* (massa) | ||
sigma' = sigma/sigma* (distância) | ||
epsilon' = epsion/epsilon* (energia = força*[distância]) No caso do LJ, epsilon*[distância]/distância^2 = força | ||
[xi'] = [xi]/sigma* (distância) | ||
Dimensões: | ||
|
||
comprimento sigma (LJ) | ||
energia epsilon (LJ) | ||
massa m | ||
Velocidade sqrt(epsilon/m) | ||
força epsilon/sigma | ||
pressão epsilon/sigma^3 | ||
temperatura epsilon*k_b | ||
|
||
Adimensionais | ||
|
||
[rij] = [rij]/sigma* | ||
T' = T*k_b/epsilon | ||
E' = E/epsilon* | ||
V' = V/epsilon* (energia potencial) | ||
t' = t/alpha com alpha = sqrt( (m^2*sigma^2/epsilon*) ) | ||
|
||
O que dá pra fazer aqui para admensionalizar. | ||
Escolher uma das particulas como referência, esta terá valores de | ||
sigma, m, epsilon = 1 | ||
A velocidade das partículas determinada por T ou E será o que fará as particulas | ||
se aglutinarem mais ou menos. | ||
|
||
|
||
|
||
Ek = T'* epsilon | ||
T' = Ek/epsilon (numero grande) = Ek' |
