Function/Subroutine Documentation

effic()

subroutine pmc_coag_kernel_sedi::effic	(	real(kind=dp), intent(in)	r1,
		real(kind=dp), intent(in)	r2,
		real(kind=dp), intent(out)	ec
	)

Coagulation efficiency.

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

Parameters

[in]	r1	Geometric radius of first particle (m).
[in]	r2	Geometric radius of second particle (m).
[out]	ec	Collision efficiency (dimensionless).

fall_g()

subroutine pmc_coag_kernel_sedi::fall_g	(	real(kind=dp), intent(in)	r,
		real(kind=dp), intent(out)	w_inf
	)

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

Parameters

[in]	r	Particle mobility radius (m).
[out]	w_inf	Terminal velocity (m/s).
