g_h: boundary layer conductance to heat (m / s)

Description

g_h: boundary layer conductance to heat (m / s)

Usage

.get_gh(T_leaf, surface, pars, unitless)

Arguments

T_leaf

Leaf temperature in Kelvin
surface

Leaf surface (lower or upper)
pars

Concatenated parameters (leaf_par, enviro_par, and constants)
unitless

Logical. Should function use parameters with units? The function is faster when FALSE, but input must be in correct units or else results will be incorrect without any warning.

Details

g_h = D_h Nu / d

Symbol R Description Units Default
d leafsize Leaf characteristic dimension in meters m 0.1
D_h D_h diffusion coefficient for heat in air m^2 / s calculated
Nu Nu Nusselt number none calculated

Value

Value in m/s of class units

Examples

library(tealeaves)

cs <- make_constants()
ep <- make_enviropar()
lp <- make_leafpar()

T_leaf <- set_units(298.15, K)

tealeaves:::.get_gh(T_leaf, "lower", c(cs, ep, lp), FALSE)
