CollisionIntegral-class: Class "CollisionIntegral"

Description

Class for the empirical interpolation functions for 16 reduced Lennard-Jones (12-6) collision integrals in the range 0.3 <= Θ <= 400.

Fields

l:

order of collision integral \(l\)

s:

order of collision integral \(s\)

coeff:

coefficients for collision integrals for order \(l\) and \(s\), see coefficients_collisionintegral

A:

model parameter A

B:

model parameter B₁ ... B₆

C:

model parameter C₁ ... C₆

Methods

initialize(s, l):

Initialize reduced collision integral of order \(l\) and \(s\)

Omega(Theta):

Calculates reduced collision integral Ω(l,s) at reduced temperature \(\Theta\) using the empirical interpolation function
