Function Documentation

subroutine pmc_kernel_sedi::effic ( real*8,intent(in)  r1,
real*8,intent(in)  r2,
real*8,intent(out)  ec 
)

Coagulation efficiency.

Determines the chance that two particles will actually coagulate, given that they approach close enough to do so.

Parameters:
r1 Radius of first particle (um).
r2 Radius of second particle (um).
ec Collision efficiency (dimensionless).
subroutine pmc_kernel_sedi::fall_g ( real*8,intent(in)  r,
real*8,intent(out)  w_inf 
)

Finds the terminal velocity of a particle based on its size.

Parameters:
r Particle radius (m).
w_inf Terminal velocity (m/s).
subroutine pmc_kernel_sedi::kernel_sedi ( real*8,intent(in)  v1,
real*8,intent(in)  v2,
type(env_state_t),intent(in)  env_state,
real*8,intent(out)  k 
)

Sedimentation coagulation kernel.

Parameters:
v1 Volume of first particle (m^3).
v2 Volume of second particle (m^3).
env_state Environment state.
k Kernel k(a,b) (m^3/s).
