probe_eff: Probe efficiency

Description

In order to run this function, first produce a particle distribution with the `particle_dist` function, then produce a parameter set with the `set_params` function. Both of these results must be stored as per examples described in the help set with each.

Usage

probe_eff(df, params, orient = "u", method = "blunt pipe")

Value

data frame containing original particle distribution with added data for this element

Arguments

df

is the particle data set (data frame) established with the `particle_dist` function

params

is the parameter data set for parameters that are not particle size-dependent

orient

orientation of the probe. Options are 'u' for up, 'd' for down, and 'h' for horizontal

method

is the model for the probe efficiency. Default is 'blunt pipe', based on Su WC and Vincent JH, Towards a general semi-empirical model for the aspiration efficiencies of aerosol samplers in perfectly calm air, Aerosol Science 35 (2004) 1119-1134

Examples

df <- particle_dist() # set up particle distribution
params <- set_params_1("D_tube" = 2.54, "Q_lpm" = 100,
"T_C" = 25, "P_kPa" = 101.325) #example system parameters
df <- set_params_2(df, params) #particle size-dependent parameters
df <- probe_eff(df, params, orient = 'u') #probe orientation - draws upward
head(df)
