shamrock.external.coala.kernel_collision.k_Br

shamrock.external.coala.kernel_collision.k_Br(K0, u, v)

Function to compute collision kernel from Brownian motion, K = sigma * dv

Parameters

K0scalar, type -> float

constant value of the kernel function (used to adapt to code unit)

uscalar, type -> float

mass variable (colliding grain of mass u)

vscalar, type -> float

mass variable (colliding grain of mass v)

Returns

resscalar, type -> float

Brownian motion collision kernel
